* chore: remove unreachable dead code across the codebase
Remove ~50,000 lines of unreachable code identified by static analysis.
Major removals:
- weed/filer/redis_lua: entire unused Redis Lua filer store implementation
- weed/wdclient/net2, resource_pool: unused connection/resource pool packages
- weed/plugin/worker/lifecycle: unused lifecycle plugin worker
- weed/s3api: unused S3 policy templates, presigned URL IAM, streaming copy,
multipart IAM, key rotation, and various SSE helper functions
- weed/mq/kafka: unused partition mapping, compression, schema, and protocol functions
- weed/mq/offset: unused SQL storage and migration code
- weed/worker: unused registry, task, and monitoring functions
- weed/query: unused SQL engine, parquet scanner, and type functions
- weed/shell: unused EC proportional rebalance functions
- weed/storage/erasure_coding/distribution: unused distribution analysis functions
- Individual unreachable functions removed from 150+ files across admin,
credential, filer, iam, kms, mount, mq, operation, pb, s3api, server,
shell, storage, topology, and util packages
* fix(s3): reset shared memory store in IAM test to prevent flaky failure
TestLoadIAMManagerFromConfig_EmptyConfigWithFallbackKey was flaky because
the MemoryStore credential backend is a singleton registered via init().
Earlier tests that create anonymous identities pollute the shared store,
causing LookupAnonymous() to unexpectedly return true.
Fix by calling Reset() on the memory store before the test runs.
* style: run gofmt on changed files
* fix: restore KMS functions used by integration tests
* fix(plugin): prevent panic on send to closed worker session channel
The Plugin.sendToWorker method could panic with "send on closed channel"
when a worker disconnected while a message was being sent. The race was
between streamSession.close() closing the outgoing channel and sendToWorker
writing to it concurrently.
Add a done channel to streamSession that is closed before the outgoing
channel, and check it in sendToWorker's select to safely detect closed
sessions without panicking.
* Fix: prevent panic when swap file creation fails
* weed mount: fix race condition in swap file initialization
Ensure thread-safe access to sf.file and other state in NewSwapFileChunk
and FreeResource by using sf.chunkTrackingLock consistently. Also
set sf.file to nil after closing to prevent reuse.
* weed mount: improve swap directory creation logic
- Check error for os.MkdirAll and log it if it fails.
- Use 0700 permissions for the swap directory for better security.
- Improve error logging context.
* weed mount: add unit tests for swap file creation
Add tests to verify:
- Concurrent initialization of the swap file.
- Correct directory permissions (0700).
- Automatic directory recreation if deleted.
* weed mount: fix thread-safety in swap file unit tests
Use atomic.Uint32 to track failures within goroutines in
TestSwapFile_NewSwapFileChunk_Concurrent to avoid unsafe calls to
t.Errorf from multiple goroutines.
* weed mount: simplify swap file creation logic
Refactor the directory check and retry logic for better readability and
to avoid re-using the main error variable for directory creation errors.
Remove redundant error logging.
* weed mount: improve error checking in swap file tests
Explicitly check if NewSwapFileChunk returns nil to provide more
informative failures.
* weed mount: update DirtyPages interface to return error
Propagate errors from SaveDataAt when swap file creation fails. This
prevents potential panics in the write path.
* weed mount: handle AddPage errors in write paths
Update ChunkedDirtyPages and PageWriter to propagate errors and update
WFS.Write and WFS.CopyFileRange to return fuse.EIO on failure.
* weed mount: update swap directory creation error message
Change "recreate" to "create/recreate" to better reflect that this path
is also taken during the initial creation of the swap directory.

Fixes:
1. set start and stop offset for the value object
2. clone the value object
3. use pointer instead of copy-by-value when passing to interval.Value
4. use insert interval since adding chunk could be out of order
