Use make([]NthParts, 0, len(indexes)) so the slice starts empty with
reserved capacity. The previous length-len(indexes) allocation left
leading zero NthParts entries before appended elements.
- Changed +m to --multi to enable multi-select in CTRL-R
- Changed exclude to exclude-multi and {1} to {+1} so
shift-delete removes all selected entries at once
When --walker=follow is used, symlinks like Wine's z: -> / cause fzf to
traverse the entire root filesystem. fastwalk's built-in loop detection
only catches this on the second pass, but a single pass through / already
causes severe CPU and memory exhaustion.
This fix resolves each symlink-to-directory target to its absolute real
path and skips it if it is an ancestor of (or equal to) the walker root.

When --walker=follow is used, symlink following is now handled by
fastwalk's IgnoreDuplicateDirs adapter which tracks visited directories
by device+inode. This prevents the same directory from being entered
more than once, avoiding effectively infinite traversal when a symlink
points outside the walker root.

Separate item identity from cursor tracking:
- Add --id-nth=NTH to define item identity fields for cross-reload ops
- --track reverts to a simple boolean flag
- track-current action no longer accepts nth argument
- With --multi, selections are preserved across reload-sync by matching
identity keys in the reloaded list

Allow --track to accept an optional nth expression for cross-reload
tracking. When a reload is triggered, fzf extracts a tracking key from
the current item using the nth expression, blocks the UI, and searches
for a matching item in the reloaded list.
- --track=.. tracks by entire line, --track=1 by first field, etc.
- --track without NTH retains existing index-based behavior
- UI is blocked during search (dimmed query, hidden cursor, +T*/+t*)
- reload unblocks eagerly on match; reload-sync waits for stream end
- Escape/Ctrl-C cancels blocked state without quitting
- track-current action accepts optional nth: track-current(1)
- Validate nth expression at parse time for both --track and track()
- Cache trackKeyFor results per item to avoid redundant computation
- Rename executeRegexp to argActionRegexp

Fix#4709
Use go-shellwords instead of strings.Fields to parse --with-shell,
so paths with spaces can be properly quoted.
ln -s /bin/bash "/tmp/ba sh"
fzf --with-shell='/tmp/ba\ sh -c' --preview 'echo hello world'
fzf --with-shell='"/tmp/ba sh" -c' --preview 'echo hello world'
Replace the per-chunk query cache from []Result slices to fixed-size
bitmaps (ChunkBitmap: [16]uint64 = 128 bytes per entry). Each bit
indicates whether the corresponding item in the chunk matched.
This reduces cache memory by 86 times in testing:
- Old []Result cache: ~22KB per chunk per query (for 500 matches)
- New bitmap cache: ~262 bytes per chunk per query (fixed)
With the reduced per-entry cost, queryCacheMax is raised from
chunkSize/5 to chunkSize/2, allowing broader queries (up to 50% match
rate) to be cached while still using far less memory.
Fixes bugs reported in https://github.com/junegunn/fzf/pull/4703:
* Clamp followOffset return value to avoid going past the end of lines
* Account for t.previewed.filled when determining scrollability
