autonomic-bot 2cede01ed7 style(1b): auto-format + lint-clean the whole codebase (RL1)
Mechanical, semantics-preserving cleanup so the codebase passes the new lint stage:
- ruff format: all 32 Python files (wraps long signatures, normalizes quotes/blank lines).
- nixpkgs-fmt: modules/drone-runner.nix.
- shfmt (-i 2 -ci): scripts/*.sh.

Lint fixes (reviewed, behavior-preserving — no test weakened):
- ruff SIM105: try/except-pass -> contextlib.suppress (abra.py app_config rm; lifecycle.py janitor).
- ruff SIM115: open().read() -> with open() (run_recipe_ci.py redaction-values + gitea-token).
- statix: merge repeated sops `secrets.*` keys into one `secrets = { ... }` (comments kept);
  empty fn pattern `{ ... }:` -> `_:` (packages.nix).
- deadnix: drop unused lambda args (flake `self`; configuration.nix `lib`; overlay `final` -> `_`).

Verified on cc-ci: `scripts/lint.sh` -> lint: PASS; nixosConfigurations.cc-ci evaluates;
all Python byte-compiles. The deployed bridge/dashboard/runner source changes hash (reformat),
so cc-ci will be rebuilt to the new closure in W2 before the cold D1-D10 re-verification.

# sops-nix wiring (D6 infra secrets). cc-ci decrypts secrets at activation using its own
