release: 3.6.0

[piwi3910]

procoder release 3.6.0 reports ready:

release 3.6.0 is ready — tag it:
  git tag -a v3.6.0 -m "3.6.0"

Nine version files and the changelog heading. The entries themselves landed with the changes they describe.

What is in it

Added — every command answers over a local socket (#272). procoder serve, one envelope, typed results beside the human bytes, jobs for the nine long-running commands, and the executing four behind their own opt-in door. [service] mode is off by default, so nothing changes for a repository that upgrades.

Fixed — a single-agent repository is no longer blocked for the eleven hosts it does not use (#280 / #279).

Fixed — the gate's hint no longer invites a one-liner that deletes a file's first line (#281 / #278).

Version

Minor over 3.5.0. New command, new config keys, changed gate output — RELEASE.md counts "what a command prints" as at least a minor bump. AGENTS.md is untouched, so ContractVersion stays at 3 and no adopter's agent is governed differently.

After merge

Tag the merged commit and push; the release job builds the five platform binaries and SHA256SUMS from the tag. Nothing is built locally.

🔵 Needs a closer look

The 3.6.0 changelog entry’s summary contains truncated sentence fragments that should be corrected before tagging the release.

Review details

CHANGELOG.md:58

• The release summary contains two truncated fragments ("had no reason to..." and "uses one agent...") that read like incomplete sentences, breaking the changelog’s own template requirement for a single coherent one-sentence summary line.

## 3.6.0 — 2026-09-09

_Every command can be called instead of spawned, and two ways procoder
could cost you something are closed._
