feat: Add guild charters and task boards for various components

- Introduced guild charters for Scanner Deno, PHP, Ruby, Native, WebService, Java, Surface.Env, Surface.FS, Surface.Secrets, Surface.Validation, UI, Zastava Observer, Zastava Webhook, Zastava Core, and Plugin Platform.
- Each charter outlines the mission, scope, required reading, and working agreements for the respective guilds.
- Created task boards for Surface.Env, Surface.FS, Surface.Secrets, Surface.Validation, and Zastava components to track progress and dependencies.
- Ensured all documents emphasize determinism, offline readiness, security, and integration with shared Surface libraries.

+| LANG-SURFACE-01 | TODO | Language Analyzer Guild | SURFACE-VAL-02, SURFACE-FS-02 | Invoke Surface.Validation checks (env/cache/secrets) before analyzer execution to ensure consistent prerequisites. | Validation pipeline integrated; regression tests updated; failures bubble with actionable errors. |
+| LANG-SURFACE-02 | TODO | Language Analyzer Guild | SURFACE-FS-02 | Consume Surface.FS APIs for layer/source caching (instead of bespoke caches) to improve determinism. | Analyzer outputs match baseline; performance benchmarks recorded; docs updated. |
+| LANG-SURFACE-03 | TODO | Language Analyzer Guild | SURFACE-SECRETS-02 | Replace direct secret/env reads with Surface.Secrets references when fetching package feeds or registry creds. | Analyzer uses shared provider; tests cover rotation/failure; config docs updated. |
