* feat(#1724): complete install write-confinement (copyWithPathReplacement, installCodexConfig)

ADR-1239 Phase B (parent #1679). PR #1706 (2a) confined the layout-driven
plan path and _copyStaged's inline guard; this completes the destSubpath
write-confinement acceptance criterion for the two remaining write sites
and canonicalizes _copyStaged.

- copyWithPathReplacement: new required confinementRoot param; a fail-closed
  gate (assertDestWithinConfigHome + hasExistingSymlinkBetween) runs BEFORE
  the rmSync/mkdirSync; root threaded through recursion + all 4 call sites
  (stageRoot for pristine staging, targetDir for the 3 install sites); writes
  go through the validated absolute path. Exported for behavioral testing.
- installCodexConfig: confines config.toml, agents/, and per-agent
  agents/<name>.toml (name from agent frontmatter) via the canonical gate +
  symlink-escape guard (parity with the other two functions).
- _copyStaged: fail-closed when configDir omitted (all callers pass it);
  delegates strict-subpath to the canonical gate, keeps its symlink guard,
  writes through the validated absolute path.

Reuses the existing assertDestWithinConfigHome (handles absolute dests via
path.resolve) and hasExistingSymlinkBetween — no new module. Behavioral
regression tests (escape/dest==root/fail-closed/symlink/name-injection),
red-first proven; cross-platform symlink tests use t.skip not bare return.

Closes #1724

Changeset Fragments

This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.

Why

Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.

See #2975 for the full rationale.

Adding a fragment

node scripts/changeset/new.cjs \
  --type Fixed \
  --pr 1234 \
  --body "fix the thing — explain the user-visible change in one sentence"

This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.

Format

---
type: Fixed
pr: 1234
---
**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.

Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.

Opting out

PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.

At release time

Promotion is automatic. The release workflow's finalize job runs:

node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD --allow-empty

This reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, and deletes consumed fragments. The --allow-empty flag ensures a no-change release still gets a dated heading (with a _No notable changes._ placeholder). A subsequent verify step confirms the promotion landed correctly. Maintainers do not run this by hand.

Archived fragments

.changeset/archived/ holds fragments for already-shipped releases (≤ 1.3.1), retained for provenance. Their content was hand-curated into the dated ## [1.x.y] sections of CHANGELOG.md during the #690 backfill — they were never consumed by render. All changeset tooling enumerates .changeset/ non-recursively, so archived fragments are never picked up or rendered. Do not move them back to the top level.
