fix(indexer): emit exact file paths for the root component instead of a glob

[MrSampson]

Summary

deriveComponents() in src/extractors/indexer.ts emits paths: [dir + "/**"] for every component derived from the directory layout. For the root-level component (dir === ".", holding files with no directory — README.md, package.json, etc.), this produces paths: ["./**"].

Two downstream path matchers read that glob inconsistently:

• src/core/glob.ts's norm() strips a leading ./ before matching, so "./**" normalizes to "**", which matches every file in the repo, not just root-level ones.
• src/wiki/wiki.ts's globPrefix()/owns() do not strip the leading ./: globPrefix("./**") returns "./", and owns() then checks f.startsWith("./") against a real file path like "README.md" — which is never true. So the wiki's root component page currently owns nothing.

So the same "./**" glob simultaneously over-matches in one consumer and under-matches in another, depending on which one reads it.

Fix

Root-level files are a small, static set — list them exactly instead of globbing:

paths: dir === "." ? [...fileSet].sort() : [dir.endsWith("/") ? dir + "**" : dir + "/**"],

pathMatchesGlob's exact-match fast path and owns()'s exact/prefix check already handle a glob-char-free path correctly, so no changes were needed to glob.ts or wiki.ts — confined to the one producer.

Test plan

• New test in test/indexer.test.ts: a fixture repo with a root-level file and a src/ file — asserts the root component's paths is an exact file list with no glob characters, and that a non-root component is unaffected (still gets a directory glob).
• New test in test/wiki.test.ts: constructs the fixed shape directly (paths: ["README.md"]) and confirms assemblePack's existing owns()/globPrefix() machinery already handles it correctly — proving the practical downstream fix without needing any change in wiki.ts itself.
• Full suite: 1153 tests, 1151 pass, 1 skipped, 1 pre-existing unrelated failure (team-route-contract.test.ts, a doctor schema version-string assertion, independently confirmed to fail identically on unmodified main). npm run typecheck clean.

Closing — main has already absorbed this exact fix (identical logic, same root cause, referencing the same issue #34) via a separate sync from the fork this PR was cut from. Confirmed on current main:

• src/extractors/indexer.ts's deriveComponents() already has the dir === "." ? [...fileSet].sort() : ... exact-file-list fix.
• test/indexer.test.ts already has "root-level indexed files get exact-match component paths, not a match-everything glob (issue #34)".
• test/wiki.test.ts already has "assemblePack: an indexer-derived root component owns only those files, not the whole repo (issue #34)".

Nothing in this PR adds anything main doesn't already have. Sorry for the noise — I diagnosed this independently before checking whether it had already landed.
