The profile page failed to render with "Cannot access 'h' before
initialization". The /profile/me branch destructured `signal` from
params and used it in the apiGet call, but later redeclared
`const signal = ac.signal` in the same block scope. Block-scoped const
hoisting put the earlier reference in the temporal dead zone.
Drop the redundant inner declaration and pass `ac.signal` directly to
the form submit listener.
Fixes#233

The User Profile page rendered each adopted node's relative time from
adopted_at (the adoption date) rather than the node's most recent
activity, so it always showed the time since adoption (e.g. "35 days
ago") even when the node had advertised today.
Expose last_seen on AdoptedNodeRead and render it on the profile page,
falling back to "-" when null (matching the nodes/node-detail pages).

Fix dashboard pages stalling under rapid navigation, plus reduce the cost
of the heaviest dashboard endpoint.
SPA request cancellation: apiGet never passed an AbortSignal, so navigating
away left a page's in-flight requests running — the homepage alone fires
three (/stats + two charts), the slowest being /stats. Under rapid
navigation these piled up, holding browser connections and API threadpool
threads, so the page actually wanted queued behind stale work; a late
resolver could also clobber the new page's DOM.
- api.js: apiGet accepts an optional { signal } and forwards it to fetch;
export isAbortError().
- router.js: each navigation gets an AbortController; the previous one is
aborted at the start of _handleRoute and its signal is passed to the page
handler. A navigation-generation guard stops a superseded route from
hiding the loader for the page that replaced it.
- app.js: pageHandler swallows AbortError (an intentional cancel is not an
error).
- all 11 page modules: thread params.signal into on-load apiGet calls and
guard their catch blocks with isAbortError.
dashboard/stats consolidation: collapse the 11 sequential COUNT(*) queries
into 4 using portable conditional aggregation (func.sum(case(...))) for
nodes, messages, advertisements, and user profiles. Responses are
unchanged.
Docs: extend the v0.12 "Read-Path Query Optimisations" note and add a
"Dashboard Navigation Responsiveness" note (front-end only, no action
required).
Tests: add test_stats_time_bucket_counts asserting the active/today/24h/7d
buckets. SPA bundles are gitignored and rebuilt by the Docker/CI build, so
only committed source changed; the esbuild build was run locally to
validate the JS.

Raise diff coverage above target by exercising the previously untested
lines:
- test_cli.py: invoke the `api` command with uvicorn.run mocked to assert
the default path passes the app object (no workers/factory) and that
--workers / API_WORKERS launches the env factory by import string with
the requested worker count and factory=True.
- test_app_factory.py: add METRICS_ENABLED true/false cases that toggle
the /metrics route, covering the env-bool parsing branch.

Add a --workers / API_WORKERS option so the API can run multiple worker
processes in a single container for multi-core concurrency, without
needing to scale containers (which would conflict with the api service's
fixed container_name and complicate per-stack ops/monitoring).
The existing create_app() carries hardcoded defaults (sqlite:///./
meshcore.db, Redis off), so forked workers cannot use it — they would
open the wrong database and run without caching. Add an env-driven
factory, create_app_from_env(), that rebuilds the app from APISettings
plus the CLI-only env vars (CORS_ORIGINS, METRICS_ENABLED,
METRICS_CACHE_TTL), mirroring the single-process resolution. workers > 1
runs uvicorn against this factory via an import string; workers == 1
keeps the single-process object path so local CLI flags still apply.
Wire API_WORKERS into the api compose service (default 1, unchanged
behaviour) and document it in the README (new "Scaling the API"
section + env table) and the v0.12 upgrading notes, including the
SQLite single-host caveat and the env-vs-CLI-flag note for workers.
Tests: create_app_from_env reads DB/Redis/MQTT/metrics from env,
honours explicit overrides, and derives the collector DB path from
DATA_HOME rather than the bare create_app default.

Two read-only query optimisations, no schema changes.
node-count history: replace the per-day COUNT(*) loop (up to 90 full
scans of the unindexed created_at column) with two queries — a baseline
count of nodes created before the window plus one GROUP BY date()
aggregate, accumulated into the running total in Python. Results are
identical; the baseline seed keeps pre-window nodes counted from day 0.
sender-name resolution: add resolve_sender_names() to observer_utils,
batching all pubkey prefixes into two queries (names + name tags) via an
OR of indexable LIKE 'prefix%' terms instead of two queries per prefix.
Wire it into list_messages (was ~2xN per page) and the dashboard
channel-messages loop (nested per channel x per prefix). The dashboard
recent-ads block already batches on full public keys via IN(), so it is
left as-is.
Tests: add cumulative+baseline correctness for node-count and a
multi-sender batched-resolution case for messages.

Three related performance fixes for slow (>500ms) API responses.
1. Stop blocking the event loop. Route handlers were declared `async def`
but ran synchronous SQLAlchemy queries (and synchronous Redis calls via
the cache decorator) directly on the event loop, serializing requests.
Convert all handlers to sync `def` so FastAPI runs them in its
threadpool, and make the `@cached` decorator dual-mode (sync wrapper for
sync handlers, async wrapper preserved for a future async/Postgres path).
2. Tune SQLite for concurrency. Enable WAL, busy_timeout and
synchronous=NORMAL on every connection, and size the pool above the
threadpool so handlers don't wait on connections. In-memory SQLite is
guarded (no overflow-pool kwargs).
3. Precompute an indexed `nodes.is_observer` flag. The `observer=true`
filter scanned ~68k+ event rows to find a handful of observers (the
advertisements page calls it with limit=500). Replace the 5-way OR of
subqueries with `WHERE nodes.is_observer = ?`. The collector sets the
flag on first observation (in add_event_observer); the cleanup job
clears it once a node's events are all pruned; a migration adds the
column/index and backfills from the existing union.
