feat(ci): unify issue + PR assignment behind an LLM + central areas.json

Both issue triage and PR reviewer assignment now decide *who* via an LLM,
routing from one source of truth (.github/areas.json) that replaces the
split .github/reviewers (path->owners) and .github/ISSUE_ASSIGNEES
(owner->domains) files.

Each area carries a prose definition (for the LLM), file-path prefixes (for
matching), a comp:* label, and 2+ owners. Areas cover server/runner/host,
web/desktop-app/mobile-app, one per harness group, setup/onboarding,
policies, etc.

Selection: the LLM RANKS an area's owners by fit, given the definitions +
touched files (PR) or issue text. Trusted code takes the top-ranked owner,
breaking ties by open-work load. Hard constraint: the LLM can ONLY reorder an
area's own owners -- its output is allowlist-filtered against areas.json
before any GitHub call, so a hallucinated or prompt-injected login can never
be assigned.

PR path: a fail-open gateway step (same secrets/gateway as triage, via the
OpenAI-compatible /chat/completions endpoint with a Bearer token) writes a
rank file; the assigner falls back to today's pure load-balancing if it is
absent. Only changed-file PATHS are sent to the model -- never diff contents
or PR prose. All existing reviewer invariants (exactly-1, linked-issue
adoption, reconcile, push-down, fork-only, fail-closed) are preserved.

Issue path: ALLOWED_COMPONENTS is now derived from areas.json (kills the
prior drift between issue-triage.yml and config.yaml); ranked_owners + load
tie-break replaces the issue_number % N round-robin. A maintainer-authored
issue is still assigned to its author first (unchanged).

Tests: areas.test.js guards the areas.json invariants (owners in MAINTAINER,
real comp:* labels, hzub excluded, 2+ owners, path resolution incl. the
web/ ordering and kimi/kiro prefix split). auto-assign-reviewer.test.js
keeps all 16 prior assertions green (fallback = load order) and adds 4 for
rank>load, allowlist enforcement, and adoption-overrides-rank. The live
gateway wire format + ranking quality were verified end-to-end on CI.

-# Reviewer routing map -- area -> candidate reviewers.

-# This is NOT a GitHub CODEOWNERS file. It deliberately lives at .github/reviewers
-# (a non-magic path) so GitHub's native CODEOWNERS feature does NOT auto-request
-# reviewers. All assignment is driven by .github/workflows/auto-assign-reviewer.yml,
-# which:
-#   - runs ONLY on fork PRs authored by a non-maintainer, and
-#   - assigns EXACTLY 1 load-balanced reviewer from the area(s) the PR touches
-#     (falling back to the full set of handles in this file for unowned paths).
-# So the per-area lists below are the CANDIDATE pool per area, not "everyone gets
-# requested". This is routing only -- it does not gate merge (that stays
-# Maintainer Approval + Merge Ready).
-#
-# Syntax is CODEOWNERS-like for familiarity: "<path-prefix>  @handle @handle".
-# Last matching line wins per file. Owners must be maintainers in
-# .github/MAINTAINER. Per-area owners are the top maintainers by COMBINED commit
-# count across both repos (databricks-eng/agent-framework full history +
-# omnigent-ai/omnigent), up to ~4 per area, excluding tree-wide mechanical
-# sweeps (>100 files) and non-maintainer contributors. Worth a periodic
