feat: review-minimax-run + ci-triage-minimax-run MiniMax offload wrappers

First-pass branch review and CI failure triage in MiniMax M3 sub-sessions.
Both materialise inputs themselves (no Bash in the sub-session), gate
results strictly, retry once, and follow the explore-minimax 0/1/2/3 exit
contract. Specs with RM-n/CT-n IDs; offline tests via fake seams (36
assertions). Verified live: planted-issue branch -> 5 confirmed findings,
clean branch -> NO FINDINGS, failed gac-scratch run -> correct step +
honest low confidence.

# Triage a failing Gitea Actions run in a MiniMax M3 sub-session.
# Fetches logs via gitea-agent-companion (token stays inside gac), redacts
# credential-shaped content, and has MiniMax write a structured triage file.
# Spec: specs/ci-triage-minimax-run.spec.md. Used by /ci-triage-minimax.
#
# Usage:
# ci-triage-minimax-run --repo <owner/repo> --run <N> [--job <name|id>]
# [--out <triage-file>] [--tail N] [--max-turns N] [--timeout SECS]
# [--dryrun|-n]
#
# Exit codes:
# 0 triage file written
# 1 usage/config error (bad flags, gac usage error)
# 2 gac auth/API/not-found error, MiniMax failed after retry, or timeout
# 3 triage file missing or failed the result gate after retry

You are a CI FAILURE TRIAGE agent running non-interactively. Analyse the CI
run logs provided as files in your working directory. Rules:
- Inputs (in cwd): run-logs.ndjson (log lines + metadata envelope), jobs.txt.
- Write ONLY the triage file at the path given below. Modify nothing else.
- Do not run anything. Do not suggest running full test suites or builds.
- Search the log lines for these error signatures specifically:
error:|FAILED|Traceback|exit code|denied|timeout|not found|no such|ECONN|refused
- Quote log lines verbatim. Do NOT invent step names, file paths, or causes
you cannot point to in the log. If the log is truncated or step boundaries
are partial, say so — do not improvise.
Triage file format — exactly these sections:
## Failing step
## Error excerpt (<=10 verbatim log lines)
## Probable cause (1-3 sentences, must not be empty)
## Suggested next action (ONE command or one edit description; advisory only)
## Confidence (high|medium|low, one line why)
