Gas City v1.3.3

Hotfix: fresh gascity cities can now launch built-in formulas through the
Mayor out of the box.

Highlights

• gc init --template gascity seeds the gascity/roles pack. The gascity
  template previously imported only the city-scope formulas pack, so formulas
  resolved but their coordinator targets (gc.run-operator, …) pointed at role
  agents that were never installed — formula launches failed with
  agent "gc.run-operator" not found in city.toml (#3832). New cities now add
  gascity/roles as a default rig import, pinned to the same gascity-packs
  commit as the formulas pack, and every gc rig add (including out-of-tree
  rigs) inherits the role agents automatically.
• Actionable repair hint for uninstalled pack imports. When a missing agent
  target names a declared-but-uninstalled import, gc sling/gc agent/
  gc session now print the declared source and the exact gc import install
  command instead of only a "did you mean" suggestion.
• Doctor hint fix. The rig-pack-coverage fix hint now points at city.toml
  (where [defaults.rig.imports] lives), not pack.toml.

Upgrade notes

• No migrations. Existing cities are unaffected; the seeding applies to newly
  initialized gascity-template cities. Existing cities hitting #3832 can keep
  using the documented workaround (gc import add …/gascity/roles --name gc --rig <rig> && gc import install) or re-init.
• No dependency minimum changes (dolt 2.1.4, bd v1.0.4 toolchain unchanged).

Validation

• Cherry-picks are byte-identical to the reviewed main commits (#3841, #3851).
• Full CI on PR #3875 (fast shards, cmd/gc process shards, integration) green.
• v1.3.3-rc1 draft prerelease built; linux_amd64 artifact checksum-verified and
  smoke-tested end-to-end (init seeds roles; out-of-tree rig inherits;
  <rig>/gc.run-operator resolves active).
• rc-gate.yml (CI parity, acceptance B/C, integration shards, tutorial goldens,
  GoReleaser snapshot, macOS regression) run on the release commit.
