Loki Mode v7.52.0

Codex CLI compatibility: --full-auto deprecation swept repo-wide + budget quoting hardening

• Codex --full-auto -> --sandbox workspace-write (repo-wide): Codex CLI
  v0.125+ deprecated --full-auto (removed from codex exec --help, emits a
  deprecation warning; will hard-error in a future release). Every live
  codex exec --full-auto invocation across the codebase is now
  codex exec --sandbox workspace-write (the documented replacement;
  codex exec is non-interactive by default so the loop stays autonomous).
  --skip-git-repo-check is preserved where it already applied. Swept across
  both routes and all helpers: autonomy/run.sh, autonomy/loki,
  providers/codex.sh, loki-ts/src/runner/providers.ts,
  autonomy/completion-council.sh, autonomy/grill.sh, magic/core/debate.py,
  magic/core/generator.py, autonomy/lib/wiki_llm.py, plus all user-facing
  docs. The tier path and Bun route (which previously used the broader
  danger-full-access) now converge on workspace-write, matching what
  --full-auto always expanded to. Verified empirically against codex 0.132.0
  (new flag: no deprecation warning, runs at approval: never; old flag: warns).
• Budget-file quoting footgun fixed (autonomy/lib/claude-flags.sh): the
  remaining-budget computation interpolated a file path into a python3 -c
  program, so a path containing a quote raised a SyntaxError. The path and
  numeric values now pass via os.environ (single-quoted program), matching the
  established run.sh convention. Behavior-preserving; closes the injection
  footgun.

Gates: local-ci 78/78, full pytest + bun test + bash/Bun parity green,
3-reviewer council unanimous APPROVE (2 Opus adversarial + 1 Sonnet) after a
first round that correctly rejected on a test-assertion regression (now fixed).
