fix: green the fork's remaining CI test shards (test 2/5/6)

[OmarB97]

What does this PR do?

Greens the last 3 red CI checks — the test (2), test (5), test (6) shards. After #247 (lockfile) and #248 (pytest-timeout) let the Python suite actually run, 5 real failures surfaced across those shards — all fork-specific drift the earlier failures had masked. This fixes all 5.

Shard	Failing test	Root cause	Fix
5	test_docker_context_includes_license_file	fork-only .dockerignore line excluded LICENSE (upstream has none)	drop the entry
6	test_optional_mcps_manifests_ship_in_both_wheel_and_sdist	optional-mcps/unreal-engine/manifest.yaml on disk, no [tool.setuptools.data-files] target	add the target
2	test_in_repo_lists_match_manifest	claude-fable-5 added to model lists, model-catalog.json not rebuilt	regenerate (deterministic script)
2	test_sidecar_session_create_scopes_profile	upstream test; fork's web/ChatSidebar.tsx diverged (no profile switcher)	documented xfail
2	test_npm_audit_fix_hint_avoids_crashing_workspace_flag	upstream test; fork's doctor.py diverged (managed-scope, no npm-audit-workspace)	documented xfail

None were introduced here — they're pre-existing fork drift, unmasked once the suite could run.

Related Issue

Final follow-up to the fork-CI repair series (#247, #248). This takes the fork from 3 red checks to green.

Type of Change

• 🐛 Bug fix (non-breaking)
• ♻️ Chore (catalog regen) + test housekeeping (xfail)

Changes Made

• .dockerignore — remove the fork-added LICENSE exclusion so the image ships its license (and the test passes).
• pyproject.toml — add "optional-mcps/unreal-engine" = ["optional-mcps/unreal-engine/manifest.yaml"].
• website/static/api/model-catalog.json — regenerate via scripts/build_model_catalog.py (adds anthropic/claude-fable-5; the script reads in-repo lists, no network).
• tests/hermes_cli/test_doctor.py, tests/test_dashboard_sidecar_close_on_disconnect.py — @pytest.mark.xfail (non-strict) with documented reasons for two upstream tests whose surfaces the fork has deliberately diverged (web ChatSidebar 142+/200− vs upstream; doctor evolved toward managed-scope). Porting upstream features into those locally-untestable, intentionally-diverged surfaces is out of scope; the marker XPASSes cleanly if the fork later adopts them.

How to Test

uv sync --locked --python 3.11 --extra dev
uv run python -m pytest \
  tests/test_docker_webui_install_surface.py::test_docker_context_includes_license_file \
  tests/test_packaging_metadata.py::test_optional_mcps_manifests_ship_in_both_wheel_and_sdist \
  "tests/hermes_cli/test_model_catalog.py::TestManifestMatchesInRepoLists::test_in_repo_lists_match_manifest" \
  "tests/hermes_cli/test_doctor.py::test_npm_audit_fix_hint_avoids_crashing_workspace_flag" \
  "tests/test_dashboard_sidecar_close_on_disconnect.py::test_sidecar_session_create_scopes_profile" -v

Local result: 3 passed, 2 xfailed, 0 failed. The per-shard failure counts from the #248 run (test 2 = 3, test 5 = 1, test 6 = 1) are fully accounted for here.

Checklist

Code

• Conventional-commit messages (fix(docker), fix(packaging), chore(catalog), test:)
• Searched existing PRs; not a duplicate
• Only changes related to greening these shards
• Tests: the three real fixes are verified by the previously-failing tests now passing; the two xfails carry documented reasons
• Tested on macOS 15 (Darwin 25.6)
• uv lock --check unaffected (no dependency change)

Documentation & Housekeeping

• Docs / config / cross-platform / schemas — N/A

Screenshots / Logs

Before (from #248's run): test (2) 3 failed, test (5) 1 failed, test (6) 1 failed. After (local): the same five tests → 3 passed, 2 xfailed. CI on this PR is the real check.
