chore(release): prepare on-demand releases from the local task

+# On-demand releases
+
+Release requests are handled in the local Codex task on the maintainer's machine.
+The task reviews and adapts the analytics overlay, opens the source update PR,
+waits for CI, merges it, and dispatches `release.yml`. GitHub-hosted runners build
+and publish the cross-platform packages. No scheduled sync or homelab runner is
+required.
+
+## Prepare a source update
+
+Choose the latest published **nightly**, excluding preview releases. Pin its
+exact tag for the whole operation. Use separate clean control and candidate
+worktrees so assembling the candidate cannot overwrite the accepted controls:
+
+```bash
+git fetch origin main
+release_work=$(mktemp -d /tmp/t2-release-XXXXXX)
+for checkout in control candidate; do
+  git worktree add --detach --no-checkout "$release_work/$checkout" origin/main
+  git -C "$release_work/$checkout" sparse-checkout set --no-cone '/*' '!/.repos/'
+  git -C "$release_work/$checkout" checkout --detach
+done
+```
+
+From the control worktree, run `plan` with the selected nightly tag:
+
+```bash
+cd "$release_work/control"
+T2_SYNC_CONTEXT="$release_work/review" node .github/t2code/sync.mjs plan "$nightly_tag"
+```
+
+If it prints `release_sha` instead of `ready=true`, finish publishing that
+already accepted source before preparing a new update. The planner verifies the
+upstream release identity and ancestry. The explicit tag can skip intermediate
+nightlies while retaining the complete intervening history for review.
+
+Follow `migrate.md` against the generated review directory and pinned upstream
+Git tree. Write the review result as `review/agent-output.json` using
+`agent-output.schema.json`. Keep the fixed privacy policy and packaging controls
+intact. Run focused checks for any adapted patches.
+
+From the candidate worktree, propose the reviewed snapshot using the control
+script:
+
+```bash
+cd "$release_work/candidate"
+T2_SYNC_CONTEXT="$release_work/review" \
+  node "$release_work/control/.github/t2code/sync.mjs" propose
+```
+
+This updates the dedicated `codex/analytics-sync` branch and prints the PR number
+and candidate SHA. Wait for all checks on that exact SHA and address review
+findings. The maintainer merge path uses
+`gh pr merge --merge --admin --match-head-commit` after CI passes; do not create a
+synthetic `T2 trusted validation` status from the local account.
+
+## Publish and verify
+
+Read the merged PR's `mergeCommit.oid`, then dispatch the hosted release workflow:
+
+```bash
+gh workflow run release.yml --repo shirubasoft/t2code --ref main \
+  -f "sha=$merged_sha" -f "tag=$nightly_tag"
+```
+
+Follow the run through publication. Diagnose failures before retrying; rerun
+failed jobs when the evidence shows an external transient failure. Verify the
+published installers, CLI archives, checksums, updater manifests and provenance
+against the accepted upstream tag and merged commit. Leave any failed release
+unpublished until its checks pass.
+
+After publication, remove the temporary worktrees with `git worktree remove`
+and keep the main checkout current. Review artifacts are temporary and must not
+be committed.
