* feat: prefer same-host worker and local EC replica
Admin executor pick ranked idle workers only, so a job whose volume
lived on full-03 could still run on full-01 and pull the whole .dat
across the LAN. Rank workers whose Hello host matches any replica
first (fallback to others if the local worker is full).
Detection named Sources[0] / the lowest server id; execute then
SyncAndSelectBestReplica and could switch the copy source to another
rack. After sync, if a replica on this machine has a complete file
count, copy from that URL so affinity and pull stay on one host.
* feat: pin scheduler jobs to replica-host workers until load K
Reserve prefers the least-loaded replica-host worker and waits while
that load is below 5 instead of spilling to a free remote worker.
K=0 restores immediate spill. Waterfill uses reservation load so four
idle preferred workers each get a job.
* feat: park scheduled jobs on per-worker admin queues
Assign a detection batch to the least-loaded replica-host worker in
one pass, then let ExecutionConcurrency goroutines pop a home-runnable
job or steal when that home queue reaches K. Dispatch no longer holds
a job in reserve-backoff, so a free worker is not blocked by another
home's pin. Tracked jobs stay pending/queued and record the home
worker for the admin UI.
* fix: rehome queued jobs when the home worker dies
A live home still pins below K. A home missing from live executors
is stolen immediately onto a free worker so a short orphaned queue
does not sit until the dispatch window ends.
* feat: wait before stealing a dead home worker queue
Orphaned queues are held for 30s so a worker reconnect blink does
not dump jobs onto other machines. After the grace, steal without K
as before. Zero disables the wait. A home that comes back during
grace keeps its queue.
* fix: late-bind EC from to worker hostname
After replicas are consistent (equal FileCount), rebind encode source
to a volume server on the same hostname as worker -address. Any port
on that host is local. Diverged FileCount still uses the max replica.
* feat: assign homeless jobs to global FIFO
Jobs whose replica hostname has no registered worker skip pin and orphan grace.
Free workers take own home, then steal at K/orphan, then leftover FIFO.
* fix: take homeless FIFO before steal for no-home workers
Workers without a replica-host match take leftover first; steal (K/orphan)
only when FIFO is empty. Home workers keep own-queue, steal, then leftover.

* plugin worker: add handler registry with job categories
Introduce a self-registration pattern for plugin worker job handlers.
Each handler can register itself via init() with a HandlerFactory that
declares its job type, category (default/heavy), CLI aliases, and a
builder function.
ResolveHandlerFactories accepts a mix of category names ("all",
"default", "heavy") and explicit job type names/aliases, returning the
matching factories. This enables workers to be configured by resource
profile rather than requiring explicit job type enumeration.
* plugin worker: register all handlers via init()
Each job handler now self-registers into the global handler registry
with its canonical job type, category, CLI aliases, and build function:
- vacuum: category=default
- volume_balance: category=default
- admin_script: category=default
- erasure_coding: category=heavy
- iceberg_maintenance: category=heavy
Adding a new job type now only requires adding the init() call in the
handler file itself — no other files need to be touched.
* plugin worker: replace hardcoded job type switch with registry
Remove buildPluginWorkerHandler, parsePluginWorkerJobTypes, and
canonicalPluginWorkerJobType from worker_runtime.go. The simplified
buildPluginWorkerHandlers now delegates to
pluginworker.ResolveHandlerFactories, which resolves category names
("all", "default", "heavy") and explicit job type names/aliases.
The default job type is changed from an explicit list to "all", so new
handlers registered via init() are automatically picked up.
Update all tests to use the new API.
* plugin worker: update CLI help text for job categories
Update the -jobType flag description and command examples to document
category support (all, default, heavy) alongside explicit job type names.
* plugin worker: address review feedback
- Add CategoryAll constant; use typed constants in tokenAsCategory
- Pre-allocate result slice in ResolveHandlerFactories
- Add vacuum aliases (vol.vacuum, volume.vacuum)
- List alias examples (ec, balance, iceberg) in -jobType flag help
- Create handlers aggregator package for subpackage blank imports so
new handler subpackages only need to be added in one place
- Make category tests relationship-based (subset/union checks) instead
of asserting exact handler counts
- Add clarifying comments to worker_test.go and mini_plugin_test.go
listing expected handler names next to count assertions
