Limit workshop refresh downloads to one worker and commit build-overlay enqueue work before writing the final job log so SQLite locks do not wedge the web process.
Before invoking l4d2ctl initialize, run each blueprint overlay's builder
synchronously and then verify that every workshop item attached to the
blueprint has a cache file on disk. If any are missing, raise a clear
error naming the overlay and the missing steam_ids — server start can't
silently mount a partial overlay where some maps are mysteriously absent
in-game.

Extends SchedulerState with running_overlays / refresh_running /
blocked_servers_by_overlay, and updates can_start with the truth table:
install and refresh_workshop_items are global mutexes; build_overlay
serializes per-overlay; server jobs block on builds for any overlay
their blueprint references.
Adds enqueue_build_overlay coalescing helper that returns an existing
queued job for the same overlay rather than inserting a duplicate.
Adds run_job dispatch for build_overlay (BUILDERS[overlay.type].build)
and refresh_workshop_items (re-fetches metadata, re-downloads on
time_updated/filename change, enqueues coalesced rebuilds for affected
overlays).

Adds l4d2web/services/overlay_builders.py with a BUILDERS dict mapping
Overlay.type to a builder class. ExternalBuilder is a no-op that just
ensures the overlay directory exists. WorkshopBuilder diff-applies
absolute symlinks under left4dead2/addons/ against the overlay's current
WorkshopItem associations: creates new ones, removes obsolete, leaves
unrelated files alone, and skips uncached items with a warning rather
than producing dangling symlinks.

Adds workshop_paths.cache_path(steam_id) returning
$LEFT4ME_ROOT/workshop_cache/{steam_id}.vpk with digit-only validation.
Adds overlay_creation.generate_overlay_path(id) and
create_overlay_directory(overlay) with exist_ok=False so a stray dir from a
prior failed delete surfaces loudly instead of shadowing fresh content.

Adds l4d2web/services/steam_workshop.py: parse_workshop_input (single ID,
URL, or multi-line batch), resolve_collection (HTTPS POST to
GetCollectionDetails), fetch_metadata_batch (HTTPS POST to
GetPublishedFileDetails with consumer_app_id == 550 enforcement that
raises WorkshopValidationError in add-mode and silently skips in
refresh-mode), download_to_cache (atomic + idempotent on mtime+size),
and refresh_all (ThreadPoolExecutor with per-item error collection).
Adds requests as an explicit dependency.

- validate instance names at the host lib and web boundary against
[a-z0-9][a-z0-9_-]{0,63} to prevent path traversal via Server.name
- fail-closed on SECRET_KEY: load_config returns None when env unset,
create_app raises if missing or "dev" outside TESTING
- close login timing oracle by hashing a dummy digest when the user
is not found, equalizing response time
- set SESSION_COOKIE_SECURE outside TESTING
- delete_instance tolerates stop_service and fusermount3 failures so
partially-initialized instances clean up without contract breaks;
drops the is_mount() preflight that violated AGENTS.md
- document claim_next_job's single-process assumption
- clarify emit_step contract via docstring
