+5 86962b242b fix(gateway): consolidate tool-loop resume + provider fixes (fix-wave A) (#2820)
Collector branch superseding the gateway tool-loop duplicate cluster and
adjacent provider fixes. Re-implemented from the best of each PR (deduped by
content, not file-overlap); every fix carries test coverage.

Gateway tool-loop resume (supersedes #1934 #2062 #2065 #2112 #2274 #2487
#2336 #2257 #2499 #2491, test #2063):
- toolLoop now persists the tool-result user turn per round (onToolResultTurn),
  so a resumed subagent job reloads a balanced transcript instead of dangling
  assistant tool-calls that non-Anthropic providers reject with
  AI_MissingToolResultsError.
- runSubagentViaGateway reconciles an already-corrupted transcript on resume:
  it heals every dangling assistant tool-call turn (not just the tail) from the
  settled subagent_tool_executions rows, re-dispatching idempotent-pending
  tools and throwing on non-idempotent, mirroring the legacy Anthropic path.
  Terminal early-return for a transcript that already reached end_turn.
- repairToolPairing() is a last-resort normalization at the chat() boundary
  (from #2336): back-fills error stubs for any assistant tool-call still
  unanswered (partial turns, provider-duplicated/dropped IDs on local models,
  length-truncated batches). No-op on balanced input.
- toModelMessages is Date-safe (Postgres timestamptz -> ISO via a JSON round
  trip at the SDK boundary, never a ::jsonb cast; degrades bigint/circular to a
  string instead of throwing) and drops non-string text blocks reasoning models
  emit that AI SDK v6 rejects (#2488).

Adjacent provider fixes:
- Model-aware default max output tokens: thinking-by-default Claude 5 models get
  headroom (gateway 32000, think 16000) while everything else stays 4096/4000,
  so DeepSeek/OpenAI subagents don't exceed provider caps (#2614 #2806).
- DeepSeek: promote reasoning_content into content when content is empty, via a
  fail-open recipe fetch shim (#2617).
- OpenRouter: map openrouter_api_key (config + env) into OPENROUTER_API_KEY
  through buildGatewayConfig; register agent.use_gateway_loop, zeroentropy and
  openrouter keys in KNOWN_CONFIG_KEYS so `config set` accepts them (#2572,
  config key from #2112).

Preserves JSONB (no JSON.stringify into ::jsonb), engine parity, source
isolation, and trust-boundary invariants. Verified with the gbrain-pr-test-env
consumer matrix (clawlancer/Postgres, gstack + hivemindos/PGLite) baseline-FAIL
-> candidate-PASS on the same repro, plus bun run verify (31/31) and 439
targeted unit + e2e tests.
