feat(supervise): non-blocking MCP — pending carries proposal id + check-proposal poll tool

Closes #412.

The supervise MCP server blocked the agent's tool call polling for the
operator's decision, and on timeout returned `status: pending` with no
proposal id and no way to poll a specific proposal — so the only way to
learn a late decision was to re-propose (a duplicate).

- `handle_tools_call` pending timeout now returns the `proposal_id` and
  points the agent at `check-proposal`.
- New `check-proposal` MCP tool: non-blocking status lookup by proposal id
  (pending | approved | modified | rejected | unknown). Reuses the queue's
  FileNotFoundError semantics; archives a decided proposal exactly like the
  synchronous path, so a pending proposal stays visible to the operator
  until it's both decided and polled.
- `TOOL_CHECK_PROPOSAL` constant, re-exported from supervise; kept out of
  TOOLS since it never becomes a Proposal.tool.

Enforcement is unchanged — the tools only propose policy; the egress proxy
and git-gate still enforce — so returning early opens no hole. Follow-ups
(git-gate reject-requeue, backpressure, notifications, web console) are in
the PRD.

+# ADR 0005: Keep tracker metadata on issues
+
+- **Status:** Accepted
+- **Date:** 2026-07-18
+- **Deciders:** didericis
+
+## Context
+
+Gitea exposes labels on both issues and pull requests. Applying the same labels
+to both copies planning metadata, creates a synchronization obligation, and
+makes disagreements between the two records possible. At the same time,
+unlabelled objects look accidental unless the repository states which object
+owns the metadata.
+
+The repository already uses issues as work items and PRs as implementations of
+those work items. At this decision's cutoff, all open PRs reference issues, but
+121 of 219 historically merged PRs do not. Manufacturing retrospective issues
+for that history would create records that never participated in planning and
+would make the issue history less truthful.
+
+## Decision
+
+Issues are the canonical tracker records and own labels. Every issue has at
+least one label. An issue opened or left without labels receives
+`Status/Needs Triage` automatically until it is classified.
+
+Pull requests carry no labels. Every new PR deliberately references at least
+one existing issue in its title or description with one of these forms:
+
+- `Closes #123`, `Fixes #123`, or `Resolves #123` when merging completes it.
+- `Part of #123`, `Related to #123`, `Refs #123`, or `References #123` when it
+  contributes without completing it.
+
+Gitea Actions enforces both PR rules as a status check and repairs the empty
+issue-label state. Branch protection makes the PR policy check required.
+
+The policy applies from 2026-07-18 onward. Existing issues may be labelled as
+they are encountered, but closed PRs are grandfathered: no retrospective
+issues or PR labels are created solely to make history conform.
+
+## Consequences
+
+- Classification, priority, and workflow metadata have one source of truth.
+- A PR's issue link is the navigation path to its planning metadata.
+- Multi-PR issues do not require copied or synchronized labels.
+- `Status/Needs Triage` is an intentional fallback, not a final
+  classification.
+- Direct issue creation remains convenient; automation repairs a missing label
+  immediately after creation because Gitea has no native required-label rule.
+- The required check must be configured in branch protection after this
+  workflow lands.

+# PRD prd-new: Non-blocking supervise (async approval + proposal polling)
+
+- **Status:** Draft
+- **Author:** didericis
+- **Created:** 2026-07-18
+- **Issue:** #412
+
+## Summary
+
+The per-bottle supervise MCP server (`bot_bottle/supervise_server.py`)
+answers `tools/call` **synchronously**: it queues the agent's proposal and
+blocks the tool call polling for the operator's decision. On timeout it
+returns `status: pending` and leaves the proposal queued — but it hands the
+agent **no proposal id** and offers **no way to poll a specific pending
+proposal**, so the only way to learn the outcome is to re-propose (a
+duplicate).
+
+This PRD makes the MCP flow non-blocking and pollable, so an approval can
+happen out-of-band (a human taking minutes-to-hours in a review console)
+without holding an HTTP request open or wedging the agent:
+
+1. Include the `proposal_id` in the `pending` response.
+2. Add a `check-proposal` MCP tool: a non-blocking status lookup by
+   proposal id.
+3. Keep the short synchronous grace window for the common "operator is
+   right there" fast path.
+
+## Problem
+
+`handle_tools_call` → `_sv.wait_for_response(...)` blocks up to
+`SUPERVISE_RESPONSE_TIMEOUT_SECONDS` (default 30s). Two problems follow:
+
+- **Human latency ≠ tool-call latency.** A real review — rendered diff,
+  RBAC routing to an approver, someone tapping approve on their phone — is
+  minutes-to-hours. Holding the MCP request open that long is fragile
+  (proxy/keepalive timeouts, the mitmproxy egress hop, and the agent
+  harness's own tool-call timeout, which a long block can trip and stall
+  the whole turn).
+- **No resume path.** The pending fallback already exists, but without a
+  proposal id and a poll tool the agent can't reconnect to that specific
+  decision — it re-proposes, duplicating the queue entry.
+
+This is also the precondition for the planned web-console human-review
+flow (RBAC, audit retention, mobile) — see issue #412.
+
+**Safety note:** the MCP tools only *propose* policy changes; enforcement
+stays at the egress proxy and the git-gate. Returning early on `pending`
+therefore opens no hole — the agent still cannot egress or push anything
+unapproved.
+
+## Goals / success criteria
+
+- A `pending` MCP response carries the `proposal_id`.
+- An agent can call `check-proposal(proposal_id)` and get the current
+  state (`pending` | `approved` | `modified` | `rejected`) **without
+  blocking** and **without creating a new proposal**.
+- The synchronous fast path (operator approves within the grace window) is
+  unchanged: the first `tools/call` still returns the decision directly.
+- No change to enforcement, attribution (source-IP → bottle), or the
+  operator-side queue/response schema.
+
+## Non-goals
+
+- The git-gate `pre-receive` path (it is synchronous by nature and cannot
+  poll — its async variant is reject-fast + re-push; tracked as a
+  follow-up).
+- Backpressure / in-flight-proposal caps.
+- MCP server→client notifications (event-driven resume).
+- Any web-console UI (this PRD is the protocol groundwork it needs).
+
+## Design
+
+### `pending` response carries the id
+
+`handle_tools_call`'s timeout branch formats the pending text with the
+`proposal.id` and a pointer to `check-proposal`, so the agent knows what to
+poll.
+
+### `check-proposal` tool
+
+A new read-only MCP tool (`TOOL_CHECK_PROPOSAL = "check-proposal"`),
+attributed to the calling bottle by source IP exactly like the proposal
+tools. Input: `{ "proposal_id": string }`. Behavior:
+
+1. `read_response(slug, id)` →
+   - **found**: archive the proposal (same terminal step the synchronous
+     path takes) and return the decision via `format_response_text`;
+     `isError` iff rejected.
+2. **not found** → `read_proposal(slug, id)` →
+   - **found**: still queued → return `status: pending`.
+   - **not found**: unknown id, or already resolved-and-archived (e.g. a
+     second poll) → return `status: unknown`, `isError: true`.
+
+Both lookups already raise `FileNotFoundError` when absent
+(`queue_store.py`), so the handler needs no new store methods. `check-`
+`proposal` is the only path (besides the synchronous response) that
+archives, so a proposal that times out to `pending` stays visible to the
+operator until it is decided and then polled.
+
+### Grace window
+
+Left at the existing 30s default (`SUPERVISE_RESPONSE_TIMEOUT_SECONDS`),
+which doubles as the instant-approve fast path. Tuning it down is an
+operator setting, not a code change; noted for the console rollout.
+
+## Implementation chunks
+
+1. **(this PR)** `TOOL_CHECK_PROPOSAL` constant; `check-proposal` tool
+   definition + `handle_check_proposal`; dispatch wiring; `proposal_id` in
+   the pending text; unit tests. Files: `bot_bottle/supervise_types.py`,
+   `bot_bottle/supervise.py` (re-export), `bot_bottle/supervise_server.py`,
+   `tests/unit/test_supervise_server.py`.
+2. **(follow-up)** git-gate `pre-receive` reject-fast + re-push.
+3. **(follow-up)** per-bottle in-flight-proposal backpressure cap.
+4. **(follow-up)** MCP notifications for event-driven resume; web-console
+   review flow (RBAC, audit retention) on top.
+
+## Open questions
+
+- Should a resolved-but-unpolled proposal auto-archive after some TTL, or
+  only on poll? (Leaning: only on poll, so a decision is never lost to a
+  reaper before the agent sees it.)
+- Does the agent harness need an explicit "you have a pending proposal"
+  nudge, or is returning `pending` from the original call enough? (Deferred
+  to the notifications chunk.)
