Creates a new training course (docs/en/docs/nextflow_triathlon/) designed as a fast-track introduction to the Nextflow ecosystem. The course covers three topics in sequence:

  • Part 1 (~45 min): Condensed version of Nextflow Run parts 1 & 2 — running pipelines, the work/ directory, -resume, channels, multi-step workflows, and containers.
  • Part 2 (~45 min): Adapted from Hello nf-core part 1 — finding and running nf-core pipelines, parameter and input validation, custom configuration, plus a new section running nf-core/rnaseq with the test profile as a bridge to Part 3.
  • Part 3 (~45 min): New content for Seqera Platform — launching nf-core/rnaseq from the Seqera Pipelines catalog at production scale (based on the Seqera Platform getting-started tutorial), then adding nf-core/demo from GitHub to demonstrate the bring-your-own-pipeline workflow.

Also includes orientation, next steps, and survey pages, mkdocs.yml nav and plugin config updates, and a note in the orientation to upgrade the Codespaces machine to 8 cores for parallel execution demos.

Improve Seqera platform part

@vdauwera @claude
Add nextflow-triathlon working directory and rewrite Part 1 docs
40cc7d0 
Adds the complete nextflow-triathlon/ working directory with scripts
(1-hello.nf, 2-inputs.nf, main.nf), modules, data files, nextflow.config,
and a solutions/ subdirectory with symlinks for self-contained testing.

Rewrites 01_run_basics.md into four sections: Hello World, Process multiple
inputs, Run a multi-step pipeline, and Configure the pipeline. The config
section introduces nextflow.config structure and profiles, setting learners
up for the nf-core pipeline demo in Part 2.

@vdauwera @claude
Split nextflow-triathlon into basics/ and nf-core/ subdirectories
9fcc3f7 
Part 1 exercises now live under nextflow-triathlon/basics/, and Parts 2/3
nf-core runs use nextflow-triathlon/nf-core/. This prevents the triathlon
nextflow.config from overriding params.input when running nf-core pipelines
from the same directory.

Also adds laptop.config (withLabel overrides capping memory to 6 GB) for
local development, and updates rnaseq docs to reflect the current pipeline
version (3.26.0, revision e7ca46272c).

Restructure Section 4 to show memory error and laptop.config fix
fa08bc9

- Show the memory failure when running rnaseq without config overrides
- Explain nf-core process labels and the withLabel: fix via laptop.config
- Transition to Seqera Platform as the path to real-scale analysis
- Add link to Seqera academic program

Integrate Nextflow Triathlon into the training portfolio as a Trainin…
c10e8b2 
…g Collection

Replaces the Nextflow Run course with Triathlon Part 1, extracts a new
standalone nf-core Run course from Hello nf-core's demo-pipeline lesson
(extended with a pull-and-run nf-core/rnaseq section from Triathlon
Part 2), adds a new Seqera Platform side quest from Triathlon Part 3,
and ties the three together in a new "Nextflow Triathlon" Training
Collection. The old Nextflow Run course is retired to a browsable but
unlisted archive path; the standalone Triathlon course and its exercise
code are removed now that their content has been redistributed.

Split nav into Users/Developers groups and retire Learning Paths section
c897d30 
- Add non-clickable sidebar group labels (Users/Developers) via a custom
  nav.html override, driven by extra.nav_group_labels in mkdocs.yml
- Move Help under Home; add new Run with Seqera course (moved out of
  Side Quests) under the Users group
- Rename nf-core Run -> Run nf-core, Run on Seqera -> Run with Seqera,
  and Hello nf-core -> Build with nf-core for clarity
- Flatten Training Collections into a Learning Paths label, then retire
  it entirely: fold Architect's Toolkit into a "Suggested path" section
  on the Side Quests index, drop Nextflow Triathlon (now redundant with
  the Users course ordering), and add redirects for the old URLs
- Sync the corresponding renames/labels across all translated mkdocs.yml
  and content files where the old names were embedded as literal terms
@vdauwera
Add Setup & Help nav group and Overview sub-items across course sections
41776a4 
- Introduce a generic nav_title_overrides mechanism in mkdocs_hooks.py so
  a section's sidebar title can differ from its index page's own title
- Move Training Environment out of Help into its own top-level item, then
  group it with the version/help reference pages under a new "Setup & Help"
  label at the bottom of the nav
- Rename each course section's first sub-item to "Overview" (Nextflow Run,
  Run nf-core, Run with Seqera, Hello Nextflow, Build with nf-core,
  Nextflow for Science, Side Quests) to avoid repeating the section name,
  without changing the underlying page's own title
- Restructure the Side Quests catalog into a single HTML table with
  colspan category-separator rows, with matching CSS for the header/
  category row styling
- Sync all of the above to translated mkdocs.yml files, using each
  language's own already-translated titles where they exist
@vdauwera
Sync Overview labels and add categorized separators to Side Quests nav
924c33b 
- Extend nav_title_overrides usage to Nextflow for Science and Side Quests
  so their first sub-item reads "Overview" too, and add a matching
  nav_child_title_overrides mechanism so that label can be translated
  per language (it was previously always English, set once in the shared
  nav list)
- Reorder the Side Quests nav to match the catalog table's categories,
  and add a nav-item.html override so non-clickable category separators
  can be injected into a nested nav list, not just the top-level one
  (new nav_section_separators config, reusing the existing group-label
  styling)
- Sync all of the above to translated mkdocs.yml files

Declare mkdocs-redirects as a build dependency
28b341b 
The redirects plugin (enabled earlier for the retired Training Collections
URLs) was only present because the local Docker preview image happens to
bundle it via its squidfunk/mkdocs-material base image. Neither the
Netlify preview build (_scripts/docs.py, via its uv inline deps) nor the
production docs.yml workflow installed it, so both failed with
"Config value 'plugins': The redirects plugin is not installed" the
moment mkdocs.yml enabled it. Reproduced the Netlify build locally via
uv run docs.py build-all and confirmed all 11 languages now build clean.

Add redirects for pages relocated relative to master
590a989 
Covers content this branch moves that is currently live on master:
the old Nextflow Run course (now archived), the Hello nf-core lessons
renumbered down by one, and the demo lesson extracted into the new
nf-core Run course. Verified each target resolves with no plugin
warnings and spot-checked one end-to-end in the preview.

Merge master into gvda_triathlon
ad0e421 
Resolves the 8 real conflicts from ~3 months of independent master work
overlapping with this branch's restructuring:

- docs/en/docs/hello_nf-core/01_rewrite_hello.md,
  docs/en/docs/hello_nf-core/03_make_module.md,
  docs/en/docs/nfcore_run/01_run_demo.md: these are rename conflicts from
  the Hello nf-core lesson renumbering and the demo lesson's extraction
  into the new Run nf-core course. Kept this branch's part numbering and
  file structure, but adopted master's `channel.topic` (lowercase)
  correction, which matches the capitalization used everywhere else in
  that file.
- hello-nf-core/solutions/core-hello-part1/subworkflows/nf-core/
  utils_nfcore_pipeline/tests/main.nf.test(.snap): rename-detection
  misses; content is byte-identical to what's already at the renamed
  location, so resolved as-is.
- hello-nf-core/solutions/core-hello-part{2,4}/modules.json and
  core-hello-part1/modules.json (resurrected from part5 via a
  modify/delete conflict): master bumped the utils_nfcore_pipeline and
  utils_nfschema_plugin subworkflow pins; adopted those newer git_sha
  values and normalized formatting to the 4-space style used by sibling
  modules.json files elsewhere in the repo. Removed the resurrected
  core-hello-part5/modules.json since that directory was intentionally
  renamed to core-hello-part1 on this branch.

Verified with `uv run docs.py build-all` (the same command Netlify/CI
use) that all 11 languages still build cleanly after the merge.
@vdauwera
Fix inconsistent projectDir path introduced by merge conflict resolution
de852b9 
When resolving the merge conflict in this file, I kept our branch's
projectDir/launchDir/workDir values (correct: launchDir/workDir should
say nfcore-run, not hello-nf-core, since this course was extracted into
its own directory). But projectDir doesn't depend on which course
directory the student is in - it reflects Nextflow's pipeline cache
layout, which master had already updated to the current
.repos/<repo>/clones/<sha> format everywhere else in this same file
(including the configFiles line two lines below, which auto-merged
without conflict). Picking "ours" for projectDir left it mismatched
against that auto-merged configFiles line, a mismatch that didn't exist
on either side before the merge. Updated projectDir to match.
