chore: drop Homebrew + delete stale Java-era docs (CLI + MCP only)

Three changes per the post-v0.3.0 cleanup goal:

## 1. Homebrew dropped

- .goreleaser.yml: remove `brews:` block.
- release-go.yml: remove HOMEBREW_TAP_OWNER/REPO/GITHUB_TOKEN env.
- README.md: remove the `### Homebrew` install section.
- shared/runbooks/release-go.md: remove `## Homebrew tap` section and
  related cross-references.
- CHANGELOG.md / CLAUDE.md: scrub Homebrew mentions.

Not pursuing a tap — pre-built binaries from Releases + Cosign-verified
checksums cover the install surface. Saves repo creation + PAT churn.

## 2. Stale Java-era docs deleted

The entire `docs/project/` tree (architecture.md, conventions.md,
data-model.md, flows.md, ui.md, build-and-run.md) referenced Spring
Boot, application.yml, REST controllers, the React SPA, Jacoco, etc.
— all deleted in Phase 6 cutover. The content was wrong, not just
stale. CLAUDE.md is the single source of truth.

Updated PROJECT_SUMMARY.md links to point at CLAUDE.md instead.

## 3. `serve` subcommand decisively out of scope

CLAUDE.md previously said `serve: (deferred — not ported in v0.3.0)`.
Updated to state the position: codeiq has no REST API and no web UI.
Consumers use the CLI or the stdio MCP server. Java's `codeiq serve`
will not be reintroduced.

The `golang-jwt/jwt/v5` dep is transitive via the MCP SDK's auth
package (verified with `go mod why`) — not a serve-mode leftover.
CLAUDE.md note corrected.

Also drove (out-of-band) the branch-protection update:

    $ gh api -X POST .../branches/main/protection/required_status_checks/contexts \
        -f 'contexts[]=vet / test / staticcheck / gosec / govulncheck' \
        -f 'contexts[]=index perf gate (fixture-multi-lang)'

→ both Go gates now block merge on main.
