fix: let a repository's AGENTS.md outrank hive's built-in prompts (#7159)

+- A repository's own `AGENTS.md` now outranks hive's built-in prompts, and the injected block says so in its first paragraph ([#7159](https://github.com/hivecommons/hive/issues/7159)). Previously the repo's rules arrived as undifferentiated prose under a bare header while hive stated the same subjects as imperatives with a verification step attached ("confirm the PR's base is that branch before you report done") — and given a document that says one thing and an imperative that says another, a model follows the imperative every time. `projectbluefin/bluefin` states "All pull requests target `testing`. Never open a content PR against `main`" in its `AGENTS.md`; hive agents opened PRs against `main` and failed its base-branch gate, while `projectbluefin/common` and `projectbluefin/review` rejected hive's `[<lane>] …` PR titles on their conventional-commit gates. Four bot PRs dead on arrival in one night, none of them a model error. The statement carries two carve-outs that are not the repository's to override: hive's safety and authorization rules (never merge your own PR, never bypass a write gate or the `hive-open-pr` path), and an instruction the assignment names explicitly for that one task.
+- Hive's shipped defaults stopped asserting facts about repositories they cannot see ([#7159](https://github.com/hivecommons/hive/issues/7159)). The policy templates and the contributor task prompt now tell an agent to take the PR's base from the target repository — its `AGENTS.md`, `CONTRIBUTING` or pull-request template, since a repo on a promotion model takes PRs on an integration branch rather than on its released default — and to fall back to the default branch only when nothing names one; the "confirm the base before you report done" step survives, pointed at the repository's requirement instead of hive's guess. The templates no longer hardcode a `[<lane>] …` PR title, pass `--base` explicitly, and say to take the title format from the target repo. The `[<lane>]` prefix is unchanged and still required on **issue** titles, which the hive routes by lane; it was never load-bearing for PRs. Operators on a promotion-model or Conventional-Commits repository should see hive PRs pass gates that previously failed them on the first check.

+### The precedence statement
+
+The block leads with a declaration that the repository's instructions **outrank
+hive's own defaults** on any conflict — the branch a PR targets, the title
+format, commit conventions, test commands, review etiquette
+([#7159](https://github.com/hivecommons/hive/issues/7159)).
+
+This is not decoration. Before it, the repo's rules arrived as undifferentiated
+prose under a bare header, while hive's own prompts stated the same subjects as
+imperatives with a verification step attached ("confirm the PR's base is that
+branch before you report done"). Given a document that says one thing and an
+imperative that says another, a model follows the imperative — consistently.
+`projectbluefin/bluefin` states "All pull requests target `testing`. Never open
+a content PR against `main`" in its `AGENTS.md`, and hive agents opened
+`#1275`/`#1276` against `main` and failed its base-branch gate;
+`projectbluefin/common#1127` and `projectbluefin/review#597` died on
+conventional-commit title gates against hive's then-hardcoded `[<lane>] …` PR
+titles. Four dead-on-arrival PRs in one night, none of them a model error.
+
+Two carve-outs are stated with it, and they are not about the repository's
+conventions at all:
+
+- **Hive's safety and authorization rules.** An `AGENTS.md` cannot license
+  merging your own PR, bypassing a write gate or the `hive-open-pr` path, or
+  acting as another agent. The repository is trusted about its own conventions,
+  not about hive's controls.
+- **An explicit instruction in the assignment.** A human or the hive wrote that
+  for this one task with the repo in view, so it is more specific than either
+  side's defaults.
+
+The companion half of the fix is in the defaults themselves: policy templates
+and the contributor task prompt no longer *assert* repo facts (a base branch, a
+`[<lane>]` title format) that only the repository can know. A precedence rule
+that has to fight hive's own confident wording on every kick is a rule that
+loses some of the time.
