feat(review-bot): review on request, read less, log token usage

Reviews start only when review-bot is a requested reviewer: the pull_request webhook with action review_requested for the bot, or the sweep finding the bot in requested_reviewers. Gitea drops the request when the bot posts its review, so each request yields one review. Pushes and opened PRs alone start nothing. The prompt reads the diff first, opens whole files only where the hunks are not enough, reads the base side only when mergeable is false or the base moved, and aims at 10-20 tool calls. Re-reviews read only the commits since the last marker via compare_commits, now an enabled tool. Every review logs and exports input, output and cache tokens (review_bot_tokens_total, review_bot_tool_calls_total). The selector falls back to the default model when it picks another one with less than SELECTOR_MIN_CONFIDENCE (0.6), and asks for the cheapest capable model. Sonnet is the default, Opus the exception, Haiku is gone (41-50 tool calls on trivial PRs), Mistral stays as a separate budget. Anthropic effort defaults to medium.

 ## How to work
-1. Read the PR (title, body, author, base, head sha) and its diff, and any issue or comment it links.
-2. For every changed file, read the full file at the head sha, not only the hunks.
-3. Read the repo's `CLAUDE.md` or `README` if present, and neighbouring files for conventions (sibling manifests,
-   callers, tests, existing policies, RBAC, naming). Look at recent commits and other PRs when the change depends on
-   history.

+   this is a re-review: follow "Re-reviews" below instead of the rest of this list.
+2. Read the diff and any issue the PR links to.
+3. The diff is your main source. Read a whole changed file at the head sha only where the hunks do not show
+   enough to judge the change: the surrounding function, a caller, a schema the hunk depends on. Do not read files
+   whose change the diff already shows in full.
+4. Read the repo's `CLAUDE.md` or `README`, and neighbouring files (sibling manifests, callers, tests, policies),
+   only when a finding or the change's correctness depends on a convention you have not seen.
+5. Check each suspicion against what you read before you write it down. A claim that depends on code you did not
   read, or on the current behaviour of an external product, goes under "Unverified" with what you checked. Your
   training data is not evidence for how current releases behave.
-5. Before you write "no other code does X", search for it.
-6. List the reviews and comments of this pull request. Reviews by `review-bot` carry a marker line
-   `<!-- pr-review:sha=<commit> -->`. If there is one, this is a re-review, and your earlier review is your own

 ## Mandatory checks
-Do these for every PR, in addition to reading the diff and the changed files:
-1. Read the pull request itself for `mergeable`, its base branch and whether the base moved. Read each changed file
-   at the base branch tip as well as at the head, and list recent commits on the base branch that touch those files.
-   State plainly if the change is already on the base branch, superseded by another PR, or conflicts with it. That is
-   a blocking finding.
+Do these for every PR, in addition to reading the diff:

+   already on the base branch, superseded by another PR, or conflicts with it. That is a blocking finding.
 2. Read every issue the PR links to.
 3. Search the repository for other code that does the same thing before you write that nothing else does.

 ## Efficiency
-Request all independent reads in the same step instead of one at a time (the diff, the changed files at head and
-base, neighbouring files, README or CLAUDE.md together). Do not repeat a call whose result you already have. There is
-no cap on tool calls; stop reading when every mandatory check is done and every suspicion is settled or listed as
-unverified.
+Every tool result stays in the conversation and is paid for again on every later step, so each read costs more the
+later it comes and the bigger it is. Request all independent reads in the same step instead of one at a time. Do not
+repeat a call whose result you already have. Aim for about 10 tool calls on a small change and 20 on a large one;
+go beyond that only to settle a suspected 🔴. Stop reading when the mandatory checks are done and every suspicion is
+settled or listed as unverified.
