viettranx b2a74ba487 feat(skills): skill_manage tool + skill_evolve learning loop (#218)
Adds skill_manage — a first-class agent tool for creating, updating, and
deleting skills from within a conversation — paired with per-agent
skill_evolve that nudges predefined agents to capture reusable workflows.

Tool (skill_manage):
- create: write skill from SKILL.md content string (auto-grant, dep scan)
- patch: find/replace producing new immutable version (advisory-locked)
- delete: soft-delete (archive in DB, move to .trash/)
- Security guard: 25 regex patterns block shell injection, credential exfil,
  path traversal, SQL injection, privilege escalation
- Ownership enforced: only skill owner can patch/delete (admin bypass)
- Content size limit: 100KB; companion file copy: 20MB, symlink-safe (WalkDir)
- Enabled: false by default — admin opt-in per agent

Learning loop (skill_evolve, predefined agents only):
- System prompt: SHOULD/SHOULD NOT guidance for skill creation
- Budget nudges: [System] prefix at 70%/90% iteration budget (ephemeral, i18n)
- Postscript: once-per-run suggestion with explicit user consent
- Config: other_config.skill_evolve + skill_nudge_interval (default 15)

Security hardening (pre-existing + new):
- CreateSkillManaged: RETURNING id + pg_advisory_xact_lock (atomic upsert)
- GetNextVersionLocked: advisory lock for race-safe patch versioning
- Ownership checks on HTTP update/delete, gateway update, 4 grant/revoke handlers
- copyOtherFiles: filepath.WalkDir for real symlink detection

UI: Skill Learning toggle + nudge interval in Agent General Tab
i18n: backend (en/vi/zh catalogs) + frontend (en/vi/zh locale files)
