feat(#786): elevate GitHub Copilot installer — lifecycle hook + AGENTS.md (#804)

* feat(#786): elevate Copilot installer with lifecycle hook + AGENTS.md

Emit a self-contained sessionStart hook config (.github/hooks/gsd-session.json
local, ~/.copilot/hooks/gsd-session.json global) and write AGENTS.md at the repo
root (Copilot CLI reads it as primary instructions) alongside
copilot-instructions.md. The hook is an inline `command` hook (no separate hook
script), so it cannot dangle. Uninstall removes both and preserves user content.

Verified against GitHub Copilot CLI primary docs: hooks-configuration (camelCase
events, version+hooks shape, inline bash/powershell command hooks) and
add-custom-instructions (AGENTS.md read at repo root as primary instructions).

type: Added
pr: 804

The GitHub Copilot installer now reaches lifecycle-hook and instruction parity with other first-class runtimes. It emits a self-contained `sessionStart` hook config (`.github/hooks/gsd-session.json` for local installs, `~/.copilot/hooks/gsd-session.json` for global) and writes `AGENTS.md` at the repository root (which Copilot CLI reads as primary instructions) alongside `copilot-instructions.md`. The hook is an inline `command` hook with no separate script file, so it cannot dangle. Both artifacts are removed — with user-authored content preserved — on `--uninstall`. (#786)

Skills land in `~/.copilot/`. GSD installs as agent `.md` files and repository instruction files.
GSD also wires Copilot's lifecycle hooks and instruction files:
- **`AGENTS.md`** (local installs) — written at the repository root, which GitHub Copilot CLI reads as primary instructions, alongside `copilot-instructions.md`.
- **Lifecycle hook** — a `sessionStart` hook config is written to `.github/hooks/gsd-session.json` (local) or `~/.copilot/hooks/gsd-session.json` (global). It is a self-contained inline `command` hook (no separate hook script to install), so it can never reference a missing script. The hook is advisory-only: at session start it surfaces whether the project has a `.planning/` workflow.
Both are removed (and any user-authored content preserved) on `--uninstall`.
**Override the install directory:**
