Bump the centralized terminal-history defaults: tmux scrollback 50k->100k and
PTY buffer cap 2MB->32MB (trim 1.5MB->24MB). Both remain env/settings overridable
and bounds-clamped. Worst-case 20-session buffer budget rises 40MB->640MB.
Stacked on the terminal-history config commit.
Introduce src/config/terminal-history.ts: one place for terminal scrollback,
tmux history-limit, and PTY buffer byte caps, each overridable via env var or
the settings object and bounds-clamped via resolveTerminalHistoryConfig().
Defaults match the prior hardcoded values, so this is behavior-neutral. Wires
the resolver through buffer-limits, tmux-manager (incl. a setHistoryLimit so a
settings change applies live), session, server, system-routes, session-routes,
schemas, and the config port. Adds 4 optional settings keys (terminalScrollback
Lines, tmuxHistoryLimit, terminalBufferMaxBytes, terminalBufferTrimBytes) with
bounds + a trim<=max cross-check.
The mobile copy/paste overlay's "🖼 Image" button (and drag-drop / paste)
now handles real-world photo batches:
- Up to 20 images per batch, uploaded with bounded concurrency (3) and a
live "Uploading N/M…" progress toast; a final summary reports successes,
any failures, and whether the 20-cap trimmed the selection (no silent
truncation).
- Per-file upload limit raised 10MB → 50MB (MAX_PASTE_IMAGE_BYTES in
buffer-limits.ts, env-overridable) so full-resolution phone photos and
large screenshots aren't rejected.
- Very large images are downscaled to <=4096px longest edge before upload:
fixes iOS Safari's ~16.7M-px <canvas> limit (which made huge photos fail
to re-encode and fall back to an original that tripped the magic-byte
check), and keeps batch uploads fast and small.
- Fix a latent concurrency bug the batch path exposed: the first parallel
uploads to a session raced on `mkdir(.claude-images)` and the EEXIST
losers 500'd. mkdir now treats an existing real directory as success
(re-verifying it isn't a planted symlink), so concurrent uploads succeed.
Verified end-to-end in a real browser (Playwright): downscale, >10MB
server acceptance, 20-cap, 20/20 concurrent uploads landing on disk.

Allow overriding MAX_TERMINAL_BUFFER_SIZE, TRIM_TERMINAL_TO, MAX_TEXT_OUTPUT_SIZE,
TRIM_TEXT_TO, and MAX_MESSAGES via CODEMAN_* env vars, falling back to existing
defaults. Enables users with fewer sessions or more RAM to tune buffer sizes
without patching source.
Closes#48

- Add Disposable, BufferConfig, MemoryMetrics, CleanupRegistration types
- Create src/config/buffer-limits.ts with consolidated buffer size constants
- Create src/config/map-limits.ts with Map size limits to prevent unbounded growth
- Implement BufferAccumulator utility with configurable trim and onTrim callback
- Implement LRUMap with automatic eviction and O(1) operations
- Implement CleanupManager for unified resource cleanup with isStopped guard
- Add comprehensive tests for all new utilities
This lays the foundation for memory leak prevention and performance improvements.
