Add changelog-driven releases and App Home tab (#112)
* Add changelog-driven releases and App Home tab

Version the bot continuously from CHANGELOG.md (the single source of
truth for both the version and the staff-readable notes) and surface
changes to users in two ways:

- A new afterhours-release-notifier Lambda posts a "What's New" message
  to the shift channel on minor/major releases (patches stay silent).
- The bot gains an App Home "About" tab showing what it does, the
  command list, and the current version's notes.

release.yaml runs on Deploy success (not release:published — GITHUB_TOKEN
events don't start downstream workflows), checks out the deployed commit,
and tags + publishes a GitHub Release + invokes the notifier. It assumes a
dedicated, boundary-carrying OIDC role scoped to InvokeFunction on the
notifier; the account's cfn role gates role creation on that boundary.
The manual Version Bump workflow is retired. A CI guard enforces that a
CHANGELOG edit is a clean SemVer bump and that the in-package copy matches.

* Harden release workflow and regex against CodeQL findings

Address three code-scanning alerts on the PR:

- Critical (actions/untrusted-checkout): split release.yaml into a
  read-only `prepare` job that checks out and runs repo code, and a
  privileged `publish` job (contents:write + OIDC) that never checks out
  repo code — it tags, releases, and invokes purely through the GitHub
  and AWS APIs. Also assert head_branch == main.
- High x2 (py/polynomial-redos): rewrite the italic and link regexes in
  markdown_to_mrkdwn with possessive quantifiers and exclusive character
  classes so they run in linear time on adversarial input. Adds a
  regression test.

* Move release/announce into Deploy workflow to clear CodeQL

The workflow_run-triggered release.yaml kept tripping CodeQL's
privileged-context rules (untrusted-checkout, then cache-poisoning) —
CodeQL distrusts any workflow_run that checks out a ref, regardless of
the main-only guarantee, and there is no autofix.

Fold the release job into deploy.yaml gated on `needs: deploy`. A
push-to-main run is a trusted context, so checking out and running repo
code with write/OIDC is safe there. This still gates on deploy success
and serializes via the deploy concurrency group, and removes the
separate workflow entirely.

# Slack app manifest — After-Hours Shift Manager
#
# Version-controlled source of truth for the Slack app configuration. The app
# predates this file, so before applying it wholesale via the Slack manifest API,
# reconcile it against the live app config (App settings → App Manifest) so no
# existing scope or setting is dropped.
#
# The ONLY delta this release introduces is the App Home tab:
# - settings.event_subscriptions.bot_events: + app_home_opened
# - features.app_home.home_tab_enabled: true
# Neither needs a new OAuth scope, so no reinstall is required (see README →
# "Releases & versioning"). Replace <API_URL> with the SlackBotApiUrl stack output.
