fix(ci): repair the Claude bot and narrow what it can reach

Three problems, all in .github/workflows/claude-bot.yml.

It was silently dead. No comment had been posted since 2026-07-20 while
every run reported success: roughly twenty issues and pull requests each
burned 18-56 turns and up to $2.59, ended with permission denials, and
published nothing. Comment bodies are markdown, markdown is full of
backticks, and inside a quoted `--body "..."` backticks are command
substitution, so the write was rejected and a failed triage looked
exactly like a clean one. The body now goes to /tmp through Write and out
through --body-file, in every branch of both jobs, and each job re-reads
the thread afterwards so a rejected write fails loudly instead of
reporting success. The run transcript is kept as an artifact.

It could reach much further than it claimed. Both jobs that any GitHub
user can trigger declared themselves READ-ONLY in prose while holding
Bash(gh:*), which is not a GitHub-scoped allowlist: `gh alias set --shell`
runs its argument through sh -c and `gh extension install` fetches and
executes code, both as single commands whose first token is gh. That is a
general shell on a runner holding CLAUDE_CODE_OAUTH_TOKEN, which does not
expire with the job. `gh api` accepted any method, issues: write is
repo-scoped rather than issue-scoped, and `gh pr review --approve`,
`gh pr close` and `gh pr checkout` were forbidden in prose only. Those two
jobs now list the subcommands they actually run. The untrusted title and
body are fenced in tags carrying github.run_id, unguessable at the time
the issue is written, and the invariants an allowlist cannot express -
one issue number, labels and title only, /tmp as the sole writable path,
never $GITHUB_ENV - are stated explicitly. Both checkouts get
persist-credentials: false. handle-pr-fix and mention keep their
wildcards: only owners, members and collaborators can trigger them, and
narrowing the maintainer's own path risks more than it protects.

Its review hid findings and its triage quoted stale facts. "Prefer a few
high-signal findings over many low-value ones" is read literally by
Opus - it finds the bug, judges it below the stated bar and says
nothing - while the Severity and Confidence tiers already existed to do
that filtering. The review also never said that the working directory is
the base revision, so it could assert that a case was unhandled in code
the pull request had already rewritten, and label it confirmed, on an
outside contributor's first patch. Four CLAUDE.md conventions were
missing, each a guaranteed miss: openapigen's StructAllow allowlist, the
layering rules including the runtime.Runtime dispatch requirement that
silently breaks multi-node when bypassed, the assertion standard, and
golden share-link fixtures regenerated to turn a red test green. On the
triage side the invalid and duplicate branches were gated three times
over and so never fired, leaving spam to collect a full investigation and
a courteous reply; /etc/default/x-ui was given as the env file when it is
distro-dependent, making the PostgreSQL migration advice a silent no-op
on RHEL and Arch; an env list labelled "full" omitted XUI_PORT and the
XUI_TUNNEL_HEALTH_* family; XTLS was offered as a security option the
panel does not have. docs/architecture.md was invisible to both prompts
despite being maintained and already in the checkout. From the bot's own
output: it published a trigger only the maintainer can use, retitled
issues without saying so, asked for screenshots it cannot open, and once
invented a reason for a number it had miscounted.

All four jobs move to Opus 5, at xhigh effort rather than max - the
recommended tier for agentic work, and one below the overthinking that
max invites on routine triage.

               Code changes happen only when the maintainer mentions @claude.

+              Every state-changing inbound/client operation must dispatch
+              through the runtime.Runtime interface (internal/web/runtime/),
+              never straight to internal/xray/api.go - bypassing it silently
+              breaks multi-node deployments and is invisible in a single-box
+              reading of the diff. internal/util/* is leaf-only and must not
+              import service, controller or database. internal/web/dist/ and
+              frontend/src/generated/ are generated; a hand-edit is a violation.
+            - TESTS: stdlib `testing` only (no testify), table-driven with
+              `t.Run` subtests and `t.Helper()` on helpers. An assertion must
+              pin the exact value, typed error or emitted string - flag
+              `err != nil` / `len > 0` style assertions as a real finding, not a

+              `t.Cleanup`, and `httptest` for HTTP; internal/sub's
+              `initSubDB(t)` is the template.
