ci(claude-bot): structure PR review and issue triage prompts

Rework the handle-pr-review, handle-pr-fix, and handle-issue prompts to produce professional, structured output. The review job now rates findings by severity and confidence across explicit review areas and reports a Summary, Findings, and a text-only verdict in one plain comment; the fix job reuses the same lens to prioritize what it applies versus leaves for the author; issue triage gains a structured bug-confirmation format and explicit outcomes for mislabeled and not-a-bug reports, closing conservatively. Severity uses text labels to respect the no-emoji house style, and the adapted ignore-list keeps i18n and generated files flaggable.

+            REVIEW PRINCIPLES
+            - Base every finding on evidence: a specific diff hunk or a
+              file:line in the checked-out source. Never invent hypothetical
+              problems, and do not assume missing context unless the change

+            - If you are uncertain, say so explicitly; do not present an
+              assumption as fact.
+            - Prefer a few high-signal findings over many low-value ones. Do
+              not report the same issue twice and do not bikeshed style. Ignore
+              pure-formatting changes unless they reduce readability.
+            - Ignore true vendor code, lock files, and build output. Do NOT
+              ignore i18n or generated files here: a new English key missing
+              from any of the 13 internal/web/translation/ JSONs, or a
+              frontend/src/generated or frontend/public/openapi.json that would
+              be dirty after `make gen`, is a real convention violation.
+
+            REVIEW AREAS (weigh each against the diff):
+            - Correctness: logic errors, edge cases, nil/empty handling,
+              invalid assumptions, regressions.
+            - Security: authentication and authorization, input validation,
+              injection, XSS, CSRF, SSRF, path traversal, secrets exposure,
+              unsafe defaults. Pay special attention to
+              internal/web/controller/ handlers, subscription output in
+              internal/sub/, and Xray config generation in internal/xray/.
+            - Reliability: error handling, resource cleanup, timeouts, retry
+              and failure paths, child-process and goroutine failure handling.
+            - Performance: unnecessary allocations, N+1 or unbounded GORM
+              queries, expensive work in hot loops or per-request paths.
+            - Concurrency: races, deadlocks, unsynchronized shared state,
+              goroutine or task leaks (xray/mtproto child processes, cron jobs
+              in internal/web/job/).
+            - Maintainability: readability, naming, duplication, complexity.
+            - API design: backward compatibility, breaking changes, request
+              validation, error responses.
+            - Testing: missing coverage or edge-case tests, wrong assertions
+              (this repo uses the stdlib testing package only).
+            - Documentation: a new route needs an endpoints.ts entry; note any
+              needed upgrade or configuration notes.
+
+            SEVERITY (assign exactly one per finding; text labels, no emoji):
+            - Critical: security hole, data corruption, crash, privilege
+              escalation, authentication bypass, or severe regression.
+            - High: likely production bug, incorrect behavior, or a significant
+              performance problem.
+            - Medium: missing validation, an unhandled edge case, a
+              maintainability problem, or a moderate performance issue.
