* feat(observability): OpenTelemetry logs+traces with secret redaction

Part of #265. Adds opt-in OpenTelemetry (logs + traces) alongside the existing
stderr + opslog pipeline, plus secret redaction on all sinks. Default-off: with
no OTEL_* / SILO_OTEL_ENABLED config, behavior is unchanged.

Bootstrap (internal/telemetry):
- Setup() builds one shared resource, a TracerProvider (parent-based trace-id
  ratio sampler), a LoggerProvider, and the W3C TraceContext+Baggage propagator
  from env. It installs NO MeterProvider — metrics stay on Prometheus, and the
  built-in no-op global MeterProvider keeps the trace instrumentation libs from
  double-emitting. Shutdown is deferred with a flush timeout.
- Logs are bridged via otelslog fan-out (slog.MultiHandler), level-gated by the
  shared LevelVar and best-effort so a failing collector can't break the console
  or DB branches. stderr + opslog stay untouched.

Secret redaction (internal/logredact):
- A slog.Handler masks secret-keyed attributes (password, token, api_key,
  authorization, cookie, ...) — including .With-bound attrs, nested groups,
  secret-keyed group subtrees, and values behind a LogValuer — on the console
  and OTLP sinks, with a no-op fast path when a record has no secret keys.
  opslog.shouldRedact delegates to logredact.SecretKey so all sinks share one
  marker list.

Rotation is infra-managed (no custom file sink): container runtime for stderr,
collector/backend for OTLP, opslog partition-pruning for the DB. Documented in
docs/architecture/observability.md.

Verification: go build ./..., go vet, gofmt -l — clean; go test
./internal/telemetry/ ./internal/logredact/ -race pass.

AI-use disclosure: implemented with AI assistance (Claude Code), including
adversarial reviews that hardened the bootstrap and fixed two redaction leak
paths; reviewed by the author.

* refactor(observability): slog context+component sweep, sloglint gate (phase 3)

Part of #265. Builds on the OTel bootstrap + redaction commit.

Standardizes every log call site onto the context-carrying slog variants so
records correlate with the active OpenTelemetry trace, and locks the standard
in with a machine gate so future code (human- or AI-authored) can't drift back.

- Call-site sweep: converted the remaining slog.<Level>(...) calls to the
  slog.<Level>Context(ctx, ...) form wherever a context.Context is in scope
  (background/init calls with no ctx are left as-is), across 183 files. Applied
  via a type-aware AST codemod. Log levels and message strings are preserved
  verbatim; a component attr (canonical per-package name) is added to direct
  package-level slog calls. Bound-logger calls keep their existing .With
  bindings. The main.go and telemetry package conversions rode with their file
  in the previous commit to keep each file within a single commit.
- Enforcement (.golangci.yml): enable sloglint with context=scope, static-msg,
  key-naming-case=snake, no-mixed-args. After the sweep all four report zero
  violations repo-wide (tests included), so make lint / CI now blocks any
  regression to the non-context form. The gate ships with the sweep because it
  cannot be green until the legacy sites are converted.

Metrics remain on Prometheus; no behavior change to /metrics or Grafana.

Verification: go build ./..., go vet ./..., gofmt -l — clean; sloglint (all 4
rules) 0 violations repo-wide; log levels verified unchanged.

AI-use disclosure: implemented with AI assistance (Claude Code), including the
codemod; reviewed by the author.

* fix(observability): honor per-signal OTLP protocol and secret WithGroup names

Two Codex review findings on PR #290:

- telemetry: OTEL_EXPORTER_OTLP_{TRACES,LOGS}_PROTOCOL now override the
  generic OTEL_EXPORTER_OTLP_PROTOCOL per signal, so mixed collector
  setups (e.g. HTTP logs + gRPC traces) build the right exporter.
- logredact: entering a group whose name is secret-bearing (e.g.
  WithGroup("authorization")) now masks every leaf in that subtree,
  matching how slog.Group("authorization", ...) is masked as a whole.

* fix(observability): address review feedback on telemetry bootstrap

- Telemetry setup failure no longer kills boot: Setup returns usable
  no-op providers alongside the error and main logs and continues with
  telemetry disabled, honoring the best-effort contract.
- Honor OTEL_TRACES_SAMPLER (always_on/off, traceidratio, parentbased_*
  variants); unsupported values fall back to parentbased_traceidratio.
- Attach node identity as semconv service.instance.id instead of the
  non-semconv node.name.
- Rename opslog retention-scope log attrs to target_component/target_level
  so they no longer collide with the canonical component routing key, and
  tag those lines with component=opslog.
- Fix stale levelGated comment casing; use WarnContext in the telemetry
  shutdown defer; document the LogValuer double-resolve on the redaction
  slow path.

11704a1701 feat(sections): fix broken home section templates and add six new ones (#332)
* feat(sections): fix broken home section templates and add six new ones

Fixes templates that silently produced nothing:
- award_winners: hide from gallery (resolver is a stub until award data
  exists); saved sections keep resolving
- seasonal_themed: christmas/st_patricks/thanksgiving get an interim
  title-keyword resolver, and multi-theme selection skips themes without
  an executable query so a data-less theme can no longer black out the
  section during its own window (previously killed the section all of
  December)
- taste_match: empty genre now auto-picks the profile's strongest taste
  cluster (fallback: server top genre); the default preset was permanently
  empty
- because_you_watched: honor the recipe's anchor_item_id key (fetcher only
  read legacy source_item_id, so pinning an anchor did nothing)
- editorial_spotlight: reject subject_type=franchise (validated but could
  never resolve); fix drawer misrepresenting pinned presets as auto-rotate
- admin_curated_list: add a catalog-search item picker so Editor's Picks
  is actually addable; block saving an empty list; hide admin_only recipes
  from profile-facing galleries
- discovery fetchers (hidden_gems, forgotten_favorites,
  critically_acclaimed): honor single/multi library scope, intersected
  with viewer access; implement hidden_gems max_play_count

New templates: returning_shows (new season of shows you've watched),
genre_roulette (rotating top-genre spotlight with title override),
anniversaries (milestone release anniversaries this month), short_watches
(well-rated movies under a runtime cap), family_movie_night seasonal
theme (Fri/Sat evenings), and a "New in 4K" format_showcase preset via a
new sort=recent param.

Adds a blanket test asserting every visible gallery preset's defaults
pass its own recipe validation — the gap that let taste_match and
Editor's Picks ship broken. New SQL shapes validated with EXPLAIN against
the dev database.

* fix(sections): address PR #332 review findings

Codex review:
- returning_shows: the new-season file check now applies the effective
  library scope (section scope ∩ viewer-allowed, minus disabled) to
  media_files.media_folder_id, so an episode file that only exists in an
  out-of-scope folder can no longer surface the series
- buildLibraryScope: replaced the media_item_libraries row join with
  EXISTS / NOT EXISTS semi-joins. An item in several in-scope libraries
  now yields exactly one row in the non-GROUP BY rails (short_watches,
  anniversaries, seasonal keyword, format_showcase, new_to_library, ...),
  and the disabled-library check is item-level, closing the join-row leak
  where membership in an allowed library masked membership in a disabled
  one. Deny-only mode keeps the positive-membership guard, mirroring
  catalog's appendDiscoveryLibraryScope.

CodeRabbit review:
- recommendations reader: a taste cluster whose cached items are entirely
  filtered out now falls through to the next cluster / global fallback
  instead of returning an empty row
- genre_roulette: multi-library scopes get distinct rotation seeds
- returning_shows: reject negative lookback_days at validation
- shared oneOf() enum validator replaces per-recipe switch duplication
- SeasonalTitleOverride usable-filter contract covered by a direct test
- web NumberParamField: integer-only guard + step=1 (backend fields are
  Go ints; fractional values failed unmarshalling at save)
- curated list picker: search failures show an error instead of a
  misleading "No matches."; pre-existing item_ids hydrate display titles
  via the watch-detail endpoint instead of rendering raw ids
