feat: HTTPS auto-normalization; robust TLS intel UI; global rules state; clean logging; preload

- Add SSL/TLS intelligence pipeline:
  - crt.sh lookup with expired-filtering and root-domain wildcard resolution
  - live TLS version/cipher probe with weak/legacy flags and probe notes
- UI: card + matrix rendering, raw JSON toggle, and host/wildcard cert lists
- Front page: checkbox to optionally fetch certificate/CT data

- Introduce `URLNormalizer` with punycode support and typo repair
  - Auto-prepend `https://` for bare domains (e.g., `google.com`)
  - Optional quick HTTPS reachability + `http://` fallback
- Provide singleton via function-cached `@singleton_loader`:
  - `get_url_normalizer()` reads defaults from Settings (if present)

- Standardize function-rule return shape to `(bool, dict|None)` across
  `form_*` and `script_*` rules; include structured payloads (`note`, hosts, ext, etc.)
- Harden `FunctionRuleAdapter`:
  - Coerce legacy returns `(bool)`, `(bool, str)` → normalized outputs
  - Adapt non-dict inputs to facts (category-aware and via provided adapter)
  - Return `(True, dict)` on match, `(False, None)` on miss
  - Bind-time logging with file:line + function id for diagnostics
- `RuleEngine`:
  - Back rules by private `self._rules`; `rules` property returns copy
  - Idempotent `add_rule(replace=False)` with in-place replace and regex (re)compile
  - Fix AttributeError from property assignment during `__init__`

- Replace hidden singleton factory with explicit builder + global state:
  - `app/rules/factory.py::build_rules_engine()` builds and logs totals
  - `app/state.py` exposes `set_rules_engine()` / `get_rules_engine()` as the SOF
  - `app/wsgi.py` builds once at preload and publishes via `set_rules_engine()`
- Add lightweight debug hooks (`SS_DEBUG_RULES=1`) to trace engine id and rule counts

- Unify logging wiring:
  - `wire_logging_once(app)` clears and attaches a single handler chain
  - Create two named loggers: `sneakyscope.app` and `sneakyscope.engine`
  - Disable propagation to prevent dupes; include pid/logger name in format
- Remove stray/duplicate handlers and import-time logging
- Optional dedup filter for bursty repeats (kept off by default)

- Gunicorn: enable `--preload` in entrypoint to avoid thread races and double registration
- Documented foreground vs background log “double consumer” caveat (attach vs `compose logs`)

- Jinja: replace `{% return %}` with structured `if/elif/else` branches
- Add toggle button to show raw JSON for TLS/CT section

- Consumers should import the rules engine via:
  - `from app.state import get_rules_engine`
- Use `build_rules_engine()` **only** during preload/init to construct the instance,
  then publish with `set_rules_engine()`. Do not call old singleton factories.

- New/changed modules (high level):
  - `app/utils/urltools.py` (+) — URLNormalizer + `get_url_normalizer()`
  - `app/rules/function_rules.py` (±) — normalized payload returns
  - `engine/function_rule_adapter.py` (±) — coercion, fact adaptation, bind logs
  - `app/utils/rules_engine.py` (±) — `_rules`, idempotent `add_rule`, fixes
  - `app/rules/factory.py` (±) — pure builder; totals logged post-registration
  - `app/state.py` (+) — process-global rules engine
  - `app/logging_setup.py` (±) — single chain, two named loggers
  - `app/wsgi.py` (±) — preload build + `set_rules_engine()`
  - `entrypoint.sh` (±) — add `--preload`
  - templates (±) — TLS card, raw toggle; front-page checkbox

Closes: flaky rule-type warnings, duplicate logs, and multi-worker race on rules init.
