Tom Boucher 8616839cab chore: archive 463 shipped changeset fragments before wiring render (#714)
CHANGELOG promotion was a manual operator step that was never run, so 463
fragments for work already shipped in <=1.3.1 accumulated in .changeset/.
Their notes were already hand-curated into the dated [1.2.0]/[1.3.0]/[1.3.1]
CHANGELOG sections (#690 backfill, PR #694). Rendering them now would
duplicate and mis-attribute shipped work.

Move them to .changeset/archived/ (read non-recursively by all changeset
tooling, so never rendered), keeping only the 3 genuinely-unreleased
fragments at the top level. Prep for wiring `render` into the release
finalize job (#690 follow-up).

**Community .sh hooks now use `#!/usr/bin/env bash` for cross-distro portability.** The three opt-in bash hooks (`gsd-phase-boundary.sh`, `gsd-session-state.sh`, `gsd-validate-commit.sh`) shipped with `#!/bin/bash`, which fails on distros that don't ship bash at `/bin/bash` (NixOS, minimal Alpine images, some container runtimes). POSIX guarantees `/bin/sh` but not `/bin/bash`. The fix matches the convention already used in `scripts/*.sh`. Latent in the default install path because Claude Code wires hooks as `bash <path>` from `settings.json` (PATH-resolved — the script's own shebang is read as a comment), but the bug surfaces immediately if a hook is run directly (tests, future installer changes, manual debugging). Comment in `bin/install.js::buildHookCommand` updated to clarify that the runner is PATH-resolved bare `bash`, not `/bin/bash` — POSIX std PATH guarantee was the wrong rationale.
