* feat(epg): manual EPG mapping for Stalker portals
Extends the manual EPG-to-channel mapping (PR #1165) to Stalker:
- shared key helper buildStalkerEpgMappingKey — playlist-scoped
stalker:{playlistId}:{channelId} keys, mirroring the Xtream scheme
- ITV sidebar: right-click context menu with "Map EPG channel"; after
the dialog closes with a change, the bulk EPG cache is rebuilt so the
panel and row previews reflect the new mapping immediately
- withStalkerEpg().applyMappedItvEpg(): batch-resolves mappings for
rendered channels (one getEpgMappingsBatch IPC per new id set) and
overlays uploaded-XMLTV programs onto bulkItvEpgByChannel; overrides
survive ensureBulkItvEpg reloads
- stream-resolver: mapping check in loadStalkerEpgItems (detail) and
batched prefetch in loadStalkerEpgBatch (previews);
mappingCandidateKeys/prefetchEpgMappings generalized beyond Xtream
- global favorites: stalker branch for the Map-EPG menu entry (item id
extracted from the stalker::{playlistId}::{id} uid)
- docs: manual-mapping section in docs/architecture/stalker-epg.md and
a CLAUDE.md EPG bullet covering the whole mapping feature
- tests: applyMappedItvEpg suite, stalker preview mapping in the
stream-resolver spec, key-builder specs

* fix(epg): harden Stalker mapping edges found in adversarial review
- stream-resolver: stalker items resolve only the playlist-scoped
mapping key — bare tvgId/name candidates (tvgId mirrors the raw
provider id) could only produce false matches against unrelated M3U
mappings, and previews would disagree with the detail path
- applyMappedItvEpg: staleness guard after every await so an in-flight
call cannot write portal A's mapped EPG into portal B's state after
a playlist switch (the store is a root singleton)
- applyMappedItvEpg: ids are marked checked only after a successful
lookup — a transient IPC failure no longer suppresses the mapping
for the rest of the session
- live layout: post-dialog refresh re-applies overrides for the
unfiltered channel list, so an active search cannot drop the playing
channel's mapping
- global favorites: new epgMappingChanged output emitted when the
dialog actually changed a mapping; unified live tab reloads its EPG
previews in response

* feat(epg): manual EPG-to-channel mapping with mapping fallback in all EPG paths
* fix: epg mapping in live tv list
* fix(epg): harden manual EPG mapping — upgrade safety, perf, playlist-scoped keys
Follow-up fixes on top of the manual EPG-to-channel mapping feature:
- epg-database: dedupe existing epg_programs rows before creating the
unique (channel_id, start, title) index — a plain CREATE UNIQUE INDEX
crashed the EPG worker on upgrade when historical duplicates exist;
replace INSERT OR REPLACE with ON CONFLICT DO UPDATE so the
epg_programs_fts delete trigger is not bypassed (REPLACE skips delete
triggers unless recursive_triggers is on), with a plain-INSERT
fallback when the index cannot be created
- db: add idx_content_epg_channel — the mapping fallback scanned the
whole content table on every single-channel EPG lookup
- keys: scope Xtream mapping keys per playlist via shared
buildXtreamEpgMappingKey (xtream:{playlistId}:{id}) — bare stream ids
collide across portals; the backend fallback now joins categories to
resolve the playlist id
- pwa: hide "Map EPG channel" entries behind the supportsEpgMapping
capability — the menu item was a dead end in the PWA
- parser: parse the XMLTV offset sign from the string — Math.sign(0)
dropped the minutes of ±00:xx offsets
- cleanup: typed window.electron access instead of ad-hoc casts, drop
unused resolveChannelId and dialog data field, shared
EpgMappingDialogComponent.open() for all seven call sites
- dialog UX: minimum-characters search hint, save/remove snackbars,
current mapping shows the EPG channel display name,
takeUntilDestroyed on the search stream
- i18n: fill the new keys in all 17 locales
- tests: cover mapping CRUD/search escaping, the dedup-index guard,
offset parsing and playlist-scoped keys; update stale stream-resolver
specs for the new 50-item limit and 10s timeout

* fix(epg): escape backslashes in EPG channel search LIKE pattern
CodeQL js/incomplete-sanitization: a lone trailing backslash in the
search term paired with the closing wildcard under the ESCAPE clause
and corrupted the pattern.

* perf(epg): batch mapping lookups in the viewport preview queue
Expose the existing getEpgMappingsBatch operation over a new
EPG_MAPPING_GET_BATCH IPC channel and use it in resolveManualMappings —
the per-entry lookup issued one IPC round-trip per visible channel on
every scroll event.

* perf(epg): batch mapping prefetch in the collection preview loader
Resolve all candidate mapping keys for an Xtream preview batch with a
single getEpgMappingsBatch IPC call instead of per-channel lookups.
Also fix a worker early-exit: a channel without tvgId/name returned out
of the shared-iterator loop and silently killed one of the three
concurrent preview workers.
