* feat(mito): decouple compaction unit execution and publication
Execute shared-input dependency groups as independent local compaction units. Publish and acknowledge each unit separately, retain successful sibling results, and release each unit's input leases after worker apply.
Preserve picker priority, panic notifications, snapshot-free execution context, and indexed input leases. Include regression coverage for independent visibility, purge, cancellation, partial failure, and restart recovery.

* fix: align fulltext bloom tokens with matches_term and use them for LIKE
The bloom fulltext index stored tokens that did not follow
matches_term's word boundaries (`_`, ASCII next to Han, Han substrings),
so pruning dropped rows matches_term accepts.
Tokens and query probes now share the character classes of
matches_term, Han runs are indexed as bigrams, and LIKE patterns use the
same probes. The bloom blob is written under a new key; blobs from older
versions are no longer probed. Tantivy no longer serves matches_term.

* refactor(promql): centralize PromQL function registration in promql::functions
Move the PromQL scalar UDF and UDAF registrations out of the query plan
decoder into a single `promql::functions::register_promql_functions`
entry point, so plan decoding no longer has to enumerate every PromQL
function implementation. The registered function set, aliases (e.g.
`prom_holt_winters`) and registration order are unchanged.
Add a registration test pinning the full set of `prom_*` scalar
functions and the `prom_holt_winters` alias, plus a decode regression
test covering the centralized registration path.

* fix(log-store): keep the enqueued backlog on permanent object store errors
On object storage the WAL's object store sits behind OpenDAL's retry
layer, which marks every error it returns as persistent. The enqueued
mode classified create failures by that status, so a 403 or a missing
bucket was repeated every 100 ms on every create in flight, logged
nothing, and made appends hang once the sealed batches were full.
Object store errors are now classified by kind: denied access, an
invalid configuration (how OpenDAL reports a missing S3 bucket) and a
write to a missing location are non-retriable. In the enqueued mode such
an error makes the store failing instead of poisoning it: the
acknowledged backlog is kept under its sequences and bytes, its lowest
pending batch is attempted alone with a delay that doubles from 100 ms
to 30 s, appends are rejected at once with a retryable error that
carries the last object store error, and the first create that succeeds
ends the state. Stop uploads the backlog at once and reports a failure
as before. The state is logged on entry, at most once a minute while it
lasts and on exit, and exported as the `failing` gauge and the
`rejected_appends_total` counter. Conflicts, encoding and catalog errors
still poison the store; the durable mode is unchanged.
An append held back because the sealed batches are full is now counted
and timed by the stall metrics in both modes.

* docs(rfc): describe how the enqueued object store WAL handles refused creates
Describe the enqueued failure contract as the store now implements it:
non-retriable object store errors are told apart by kind because
OpenDAL's retry layer under the store marks every error persistent, a
failing store keeps its backlog and attempts it with backoff while it
rejects appends, and stop uploads the backlog at once. Add the failure
matrix row, the failing gauge and the rejected appends counter, the
sealed-batch admission limit and the stall metrics that now count it,
and the fault matrix case counts.

* fix(log-store): time the failing attempts where they start and fix two statements
The test of the attempts of a failing store now records when each

the RFC describe 30 seconds as the longest delay between two attempts,
not as a bound on when appends resume, and the RFC states that the next
append is held once seven sealed batches wait.

The manage-region-follower chain submitted its procedures with an empty
executor context: `ProcedureServiceHandler::manage_region_follower`
accepted no query context, the operator built an
`ExecutorContext::default()`, and `MetaClient` dropped the context before
delegating to `RegionFollowerClient`. The submitting user (actor) and the
procedure event metadata therefore never reached the submitted
procedures.
- `ProcedureServiceHandler::manage_region_follower` now takes a
`QueryContextRef`, consistent with `migrate_region`, `gc_regions` and
`gc_table`.
- `ProcedureServiceOperator` derives the `ExecutorContext` (actor and
`TriggerReason::Manual` event input) from the query context.
- The `RegionFollowerClient` trait methods now accept `&ExecutorContext`
and `MetaClient` forwards it, so client implementations can transport
the actor and event context on the wire.
- `procedure_event_context`/`procedure_actor` are now public so client
implementations can reuse the trusted protocol derivation.

* perf(log-store): fetch object store WAL replay segments concurrently
A region read fetched each segment only after the previous object's
entries were yielded, so a replay paid the full request latency once per
object. Fetch up to READ_PREFETCH_DEPTH (8) segments ahead, each on its
own task, and handle their outcomes in object sequence order: entries,
collected-object skips, corrupted-segment holes and errors surface
exactly as before, and dropping the stream aborts the fetches in flight.
A read holds at most eight decoded segments besides the one it yields.

* perf(log-store): raise object store WAL recovery concurrency to 64
On S3, recovery reads the header and tail of every object, about 57 to

scales with objects divided by concurrency up to 128 lanes without
throttling: about 9,500 objects recovered in 99 s at 8 and 10.5 s at
64. At 64 recovery issues about 1,800 reads per second, a third of
S3's request rate per prefix, and holds one 64 KiB tail window per
lane, 4 MiB in all.
The recovery concurrency tests now scale with the constant.

* perf(log-store): share one prefetch byte budget among object store WAL reads
Each read fetched up to eight segments ahead on its own, so regions
opened in parallel (16 by default) could together hold 128 segments of
up to max_batch_bytes each. A read now always fetches the segment it
yields next, as before, and fetches a later one only while its length
fits in a 64 MiB budget shared by every read of the store. Regions
replayed in parallel thus hold one segment each plus at most 64 MiB,
however many open at once. Nothing waits on the budget: a read that
cannot reserve stops fetching ahead until its next poll.

* fix(log-store): fail an object store WAL read whose fetch task panics
A fetch task that panicked was re-raised in the reader with

* fix(log-store): bound replay prefetch by decoded size held by fetch tasks
The prefetch reservation sat in the read's queue, so dropping a read

buffers until it next yielded. The fetch task now holds the reservation
and returns it with its outcome, so it is released with the buffers.
A reservation also counted only the encoded segment length, while a
fetched segment is held decoded. It now counts the length plus one
Record per entry, and the comment states the whole bound.

parquet column properties. Unset fields keep the SST defaults. Nested
types are rejected.
A page size below the dictionary page limit also lowers the column's
dictionary page limit: parquet sizes write batches by the dictionary
budget and keeps that size after falling back to plain encoding, which
would otherwise ignore the smaller data page limit.
