fix(queue): skip PRs with HTTP 403/404/405 merge errors instead of looping

The queue was retrying the same PR forever when merge returned HTTP 405
("User not allowed to merge PR"). This happened because ApiError was
caught by main() and returned 0, so the next tick tried the same PR again.

Changes:
- Add MergePermissionError(ApiError) for permanent merge failures (403/404/405)
- merge_pull() catches ApiError and re-raises MergePermissionError for
  these specific codes
- process_once() catches MergePermissionError, posts a comment on the PR
  explaining the permission issue, and returns 0 (moves to next tick)

The PR stays in the merge-queue label so future ticks can retry after
the permission issue is resolved (e.g., org owner grants Can-merge).

-//
-// Root cause: the runtime builds its AgentCard from config.name
-// (workspace/main.py:198), and config.name is read from the
-// CP-regenerated /configs/config.yaml whose `name:` field is the raw
-// workspace UUID — NOT the friendly name the operator sees. The friendly
-// name IS captured: POST /workspaces and PATCH /workspaces/:id (the
-// canvas Details tab) write it to the trusted workspaces.name DB column.
-// But /registry/register stores the runtime-supplied card verbatim
-// (registry.go: `agent_card = EXCLUDED.agent_card`), so the stored card
-// served at /.well-known/agent-card.json and returned to peers via
-// agent_card_url ends up with name = UUID, description = "", role = null.
-//
-// Fix shape (deliberately minimal, no contract weakening): when the
-// runtime-supplied card's `name` is empty or equals the workspace UUID
-// (the placeholder the runtime had no better value for), the PLATFORM —
-// not the agent — substitutes the friendly value from the trusted
-// workspaces row. Identity stays platform-controlled: the agent never
-// gains the ability to self-set its own name/role; the platform sources
-// it from the operator-controlled DB column. We only ever FILL gaps
-// (empty / UUID-placeholder); a card that already carries a real
-// friendly name is never downgraded.
-//
-// list_peers / the /registry/:id/peers endpoint already resolve display
-// names from workspaces.name directly (discovery.go / mcp_tools.go
-// `SELECT w.id, w.name, ...`), so peer_name in delivered message tags
-// was already correct — this fix closes the remaining surface: the
-// agent_card blob itself (canvas Agent Card / Skills view, peer
-// agent_card_url fetches, the well-known card).
-//

-// Before this package, the same regex set lived as duplicate bash

-// YAML + bash arrays generated/asserted from this package so drift
-// is detected at CI time, not at exfiltration time.

-// This file is Phase 2a of the internal#425 RFC. Phase 2b will import
