docs(#2856): add docs/RELEASE-v1.39.0-rc.6.md (#2857)

* docs(#2856): add release notes for 1.39.0-rc.6

Documents what's actually in rc.6 (= rc.5 content + version-bump only —
release/1.39.0 was not synced with main before the bump) plus the known
SDK publish failure (@gsd-build/sdk@1.39.0-rc.6 is missing from npm with
404 PUT error). Format mirrors RELEASE-v1.39.0-rc.5.md.

Closes #2856

* docs(#2856): drop SDK refs from rc.6 notes; tag git log fence

Per maintainer + CodeRabbit review:
- Strip the 'Known issue: split publish' section, the SDK pin Note, and
  the @gsd-build/sdk follow-up bullet. SDK publish failure is a known
  separate issue and shouldn't block the rc.6 docs.
- Add bash language tag to the git log fence (markdownlint MD040).

# v1.39.0-rc.6 Release Notes
Pre-release candidate. Published to npm under the `next` tag.
```bash
npx get-shit-done-cc@next
```
---
## What's in this release
**rc.6 is a republish of rc.5.** No new fixes were rolled in — `release/1.39.0`
was bumped from `1.39.0-rc.5` to `1.39.0-rc.6` without first being merged with
`main`, so the branch contents at the time of tag are byte-for-byte equivalent
to rc.5 plus the version-bump commit.
```bash
$ git log v1.39.0-rc.5..v1.39.0-rc.6 --pretty='%h %s'
388118d8 chore: bump to 1.39.0-rc.6
```
If you are already on `1.39.0-rc.5`, there is nothing new to install in rc.6.
The expected next step is an rc.7 cut that first merges `main` into
`release/1.39.0` so the eight fixes that landed after rc.5 reach the registry.

## What was in rc.5
### Fixed
**Codex hooks migrator correctness hardening** (#2809)
Five edge-cases in the `[[hooks.<Event>]]` → `[[hooks.<Event>.hooks]]` two-level
nested schema migration path, discovered across five rounds of code review:
| Finding | Fix |
|---------|-----|
| `parseHooksBody` used a bare regex (`/^([\w.]+)\s*=/`) that silently dropped hyphenated keys such as `status-message` and any quoted TOML key | Replaced with `parseTomlKey()`, the existing full TOML key parser |
| `buildNestedBlock` unconditionally emitted `[[hooks.TYPE.hooks]]` even when no handler fields were present, producing an entry with `type = "command"` but no `command` | Added guard: matcher-only / handler-field-free sections emit only the event-entry block |
| `legacyMapSections` filter used `section.path.startsWith('hooks.')` without checking the segment count, so three-segment tables like `[hooks.SessionStart.hooks]` were misclassified as event entries and re-emitted as bogus nested events | Now uses `section.segments.length === 2` (same fix previously applied to `staleNamespacedAotSections`) |
| No regression test for quoted event names containing dots — `[[hooks."before.tool"]]` has a 2-segment path but 3 dot-parts, and a `split('.')` check would misclassify it | Regression test added; quoted-dot names are correctly treated as a single two-segment namespace |
| Handler command path assertion in install tests used a regex (`/gsd-check-update\.js/`) rather than the exact absolute path | Strengthened to `assert.strictEqual` with `path.join(codexHome, 'hooks', 'gsd-check-update.js')` |
---
## What was in rc.4
### Added
**`--minimal` install flag** (alias `--core-only`) (#2762)
Writes only the six core skills needed to run the main workflow loop:
`new-project`, `discuss-phase`, `plan-phase`, `execute-phase`, `help`, `update`.
No `gsd-*` subagents are installed.
| Mode | Cold-start system-prompt overhead |
|------|-----------------------------------|
| full (default) | ~12k tokens |
| minimal | ~700 tokens |
Useful for local LLMs with 32K–128K context windows. Sonnet 4.6 / Opus 4.7 users
don't need it — the full surface is the right default for cloud models.
The install manifest records `mode: "minimal" | "full"`. Run `gsd update` without
`--minimal` at any time to expand to the full skill set.
### Fixed (rc.4)
**Codex install no longer corrupts `~/.codex/config.toml`** (#2760)
The installer now:
- Strips legacy `[agents]` (single-bracket) and `[[agents]]` (sequence) blocks
unconditionally — both are invalid in the current Codex TOML schema, regardless of
whether a GSD marker is present.
- Emits the GSD-managed hook in the shape the user's config already uses:
`[[hooks.<Event>]]` namespaced AoT if any existing hook uses that form, otherwise
top-level `[[hooks]]`.
- Migrates any legacy `[hooks.<Event>]` (map format) to `[[hooks.<Event>]]` (array
format) during write.
- Writes atomically via a temp file + `renameSync` — no partial writes.
- Validates the post-write bytes with a strict TOML parser that rejects duplicate
keys, repeated table headers, trailing bytes after values, and unsupported value
types.
- On any pre-write or write-time failure, restores the pre-install snapshot and aborts
with a clear error instead of warn-and-continue.

## Installing the pre-release
```bash
# npm
npm install -g get-shit-done-cc@next
# npx (one-shot)
npx get-shit-done-cc@next
```
To pin to this exact RC:
```bash
npm install -g get-shit-done-cc@1.39.0-rc.6
```
---
## What's next
- **rc.7** — cut from `release/1.39.0` after merging `main` into the release branch,
so the eight fixes that landed after rc.5 (#2828, #2829, #2831, #2832, #2835,
#2836, #2838, #2839) actually reach the registry.
- Run `finalize` on the release workflow to promote `1.39.0` to `latest` once an RC
with the full main-branch contents is stable.
