Budget docs: wrap-up is typical, not deterministic; [budget] logged per planner round only

- resetSettledRun clears settling and the budget ledger; a done/failed task
  revived to running now plans and claims again (was gated by the old wrap-up).
  resetTimeoutRevival calls it. Test: TestResetSettledRunRestartsBudget.
- docker-compose.yml passes the four ARTEX_*_BUDGET_* variables through.
- .env.example and README document the variables, the wrap-up, the in-memory
  ledger and the practical floor.
- llmrec: the usage sink runs even without a PostgreSQL recorder; comment fixed.
- BudgetWrapupBlocks allows update_finding_report.

Unset or empty, the boundary is on; set `ARTEX_UNTRUSTED_BOUNDARY=0` (or `false` / `off` / `no`) to disable it. Measured cost: about 154 bytes per tool result plus one system note.

+**Noise profile (off by default)**: `ARTEX_NOISE_PROFILE` paces the requests ARTEX itself sends to targets (WebFetch, http custom tools, the enrich probe). Unset or `off`, nothing changes: no limit, no cache. Set `quiet` (2 req/s per host, burst 4, 1 in flight), `balanced` (5 req/s, burst 10, 2 in flight) or `aggressive` (20 req/s, burst 40, 4 in flight), e.g. `ARTEX_NOISE_PROFILE=balanced` in `.env` or the environment. A profile also adds a small jitter, backs off on 429/503 (honouring `Retry-After`, bounded retries, GET/HEAD/OPTIONS only), and, for the http custom tools and the enrich probe, merges identical in-flight GETs of one task (per tool) and caches them briefly (60/30/10 s; never POST, PUT, PATCH or DELETE; WebFetch is paced only), and logs a per-host noise line each minute. `ARTEX_TARGET_USER_AGENT` sets a User-Agent on target requests that carry none, under a profile; empty keeps the current one. Tools launched through Bash are not paced yet.

+**Run budgets (off by default)**: `ARTEX_TASK_BUDGET_TOKENS` and `ARTEX_TASK_BUDGET_TURNS` cap a task's total spend (its planner rounds and all its workers); `ARTEX_INTENT_BUDGET_TOKENS` and `ARTEX_INTENT_BUDGET_TURNS` cap one worker run. Unset or `0` means unlimited, and nothing changes. A worker is not started when the remaining task budget cannot cover its estimated cost (the average of the task's finished workers, else 50000 tokens and 10 turns). When the remaining budget reaches the wrap-up reserve (the larger of 5% and 20000 tokens, and 2 turns), the task enters a forced wrap-up: the planner writes a summary and the final goal judgment, and workers may only write back (`record_fact`, `insert_assets`, `report_finding`, `update_finding_report`). The task then ends `done` if its goals are met, otherwise `timeout`. Budgets are kept in memory: a restart, or a revive of a finished task, starts a fresh budget. Each planner round logs a `[budget]` line. Practical floor: below 50000 tokens a task gets no worker; from 50000 to about 70000 it typically gets one worker and then the wrap-up. Pick a budget well above 70000 tokens for real exploration.
