feat(builtins): sweep of GNU/BSD compat fixes + str performance opts

Browse Source 
Addresses a broad audit of built-in shell utilities against their real counterparts: timeout gains signal delivery, -s/-k/--preserve-status/--foreground/-v, and GNU exit codes; diff defaults to normal format and gains -w/-b/-B/-i/-c/-x/-L/-s/--strip-trailing-cr and proper -r gating; find fixes -newerXY timestamp comparison direction, anchors -regex to whole paths, and gains BSD -perm +mode, -type lists, -size T/P suffixes, -E/-x/-s flags; date gains BSD -r epoch, -v adjustments, -j -f strptime, and non-greedy -I; tail/head accept obsolete -N/+N at any position with any file count; rg resolves case flags by last occurrence and gains --path-separator and clean -0 output; stat prints integer epochs for %X/%Y/%Z and gains BSD -s/-x/-t; cksum is registered as a builtin; truncate implements -o/--io-blocks and b/= size suffixes; sleep/timeout accept infinity; yes/errno/kill accept hyphen-prefixed operands; nohup -- cmd no longer runs --; which gains BSD -s.

//! Borrowing JavaScript strings at the N-API boundary.
//!
//! Node-API never hands out a pointer into a JS string's backing store: every
//! accessor writes code units into a caller-owned buffer. The copy is
//! unavoidable, the *allocation* is not — [`utf16`] and [`utf8`] read into a
//! fixed per-thread scratch arena and hand back a guard that derefs to the
//! borrowed text, releasing its range on drop. Text that fits the arena costs
//! zero allocations; longer text spills to one owned `Vec`. Several guards can
//! be live at once (diff pairs, colour palettes) — each owns a disjoint range.
//!
//! [`utf16`] is the default: it is the JS string's own encoding, so it is the
//! only accessor that never transcodes. [`utf8`] exists for algorithms that are
//! byte- or `str`-shaped (terminal escape parsing, syntect, paths). Reach for
//! [`into_string`] only when the text must outlive the N-API callback — a value
//! moved into a worker task, a channel, or an async body.
//! Short, bounded strings — ANSI colours, font names, language ids — skip the
//! arena entirely: [`InlineStr`] decodes them into a fixed-size array that
//! lives in the struct itself, so a whole options object crosses with no
//! allocation.

### Fixed
- Fixed a prompt cancelled during turn setup (Esc while the pre-stream spinner is up, after dispatch had started) vanishing entirely: it was never persisted to the session — so the `/tree` and `/branch` selectors had nothing to rewind to — and was not returned to the editor either, while its optimistic transcript row kept lingering. A prompt dropped before reaching the agent (abort or usage-preflight denial racing setup) is now handed back: the stale transcript row is removed and the typed text and image attachments are restored to the editor for editing.
- Fixed macOS `top`-style single-dash long options in the `top` shell builtin: `top -l 2 -pid 56943 -stats pid,cpu,th,mem,pstate` previously failed with `invalid value 'id' for '--pid <PIDS>'` because clap read `-pid` as `-p id`. Single-dash long spellings now parse, and `-stats` selects and orders output columns using macOS stat keys (`pid`, `cpu`, `th`, `mem`, `pstate`, ...).
- Fixed a sweep of GNU/BSD compatibility gaps in the built-in shell utilities, found by auditing every builtin against its real counterpart: `timeout` gained `-s`/`-k`/`--preserve-status`/`--foreground`/`-v`, GNU exit codes (124/125/137), signal delivery to the child process group with `-k` SIGKILL escalation, and `timeout 0` disabling the limit; `diff` gained normal-format default output, `-w`/`-b`/`-B`/`-i`/`-x`/`-L`/`-s`/`--strip-trailing-cr`, context format (`-c`/`-C`), bundled flags (`-ru`, `-urN`), timestamped unified headers, and no longer recurses directories without `-r`; `find` fixed inverted `-newerXY` timestamp comparisons, anchored `-regex` to whole paths, and gained BSD `-perm +mode`, `-type f,d` lists, `-size` `T`/`P` suffixes, ISO dates in `-newermt`, and BSD leading flags `-E`/`-x`/`-s`; `date` gained BSD `-r <epoch>`, `-v` adjustments, and `-j -f` strptime parsing, and `-I` no longer swallows a following `+FORMAT`; `tail`/`head` accept obsolete `-N`/`+N` counts at any argv position with any file count, `tail -r -n N` works, and `head` continues past per-file I/O errors with GNU header/separator placement; `rg` resolves `-s`/`-i`/`-S` by last occurrence, accepts `--no-config`/`-j`/`--threads`/`--no-column`, implements `--path-separator`, and emits clean NUL-delimited output under `-0`/`-l0`; `stat` prints integer epochs for `%X`/`%Y`/`%Z` (bash arithmetic on `stat -c %Y` works) and gained BSD `-s`/`-x` output modes plus `-t` time formatting; `cksum` is now registered (multi-algorithm `cksum -a sha256`); `truncate` implements `-o`/`--io-blocks` (previously silently truncated to the raw byte count), accepts `b` (512-byte) suffix and BSD `=` prefix; `sleep`/`timeout` accept `infinity` and keep sub-millisecond precision; `yes` and `errno` accept hyphen-prefixed operands (`yes -n`, `errno -2`); `nohup -- cmd` no longer tries to run `--` (including backgrounded via the brush wrapper); `which` gained BSD `-s` and errors on zero operands; `kill` accepts attached values (`-s9`, `-sKILL`, `-l9`) and maps exit statuses above 128 (`kill -l 137` → `KILL`).
