Julius Brussee e4e4989085 fix(xplat): stop the installer and uninstaller from breaking their own state ...

Marker handling, both directions. `installOpencode` and caveman-init treated
"both markers present" as a fence, so an orphan BEGIN or an END above a
BEGIN ran the slice arithmetic on end === -1: AGENTS.md re-appended itself
from byte 19 and compounded on every re-run, and a per-repo refresh would
have replaced everything between an orphan BEGIN and a later block's END,
user content included. Both now require exactly one matched pair, in order,
and report damage instead of writing.

Uninstall ordering. uninstall.sh/uninstall.ps1 deleted the hook files first
and edited settings.json second, so a failed or refused edit left Claude
Code pointing at scripts that no longer exist — `Cannot find module
…caveman-activate.js` on every session start (#471). Settings first; files
only once nothing references them. Neither script overwrites an existing
.bak any more (it is the user's only pre-caveman copy), and a JSONC
settings.json now aborts the edit with the working command instead of
half-uninstalling.

install.ps1's "already wired" probe matched the bare substring `caveman`,
which any user hook mentioning the word in a path satisfies (#593) — it
silently skipped wiring and left caveman inactive. It now probes for the
exact script we write per event, mirroring install.sh.

The SessionStart watchdog no longer claims `startup` when it fires. That is
the one source that resets the mode, so a payload slow enough to time out on
a compact/resume event dropped a mid-session `ultra` back to the default.
An unknown source preserves a valid existing flag, and the deadline moves to
3s — still well inside the host's 5s budget, but above a cold Windows/AV
start.

caveman-init writes retry a rename that Windows loses to OneDrive/AV
handles (EPERM/EBUSY/EACCES), the shrink MCP refuses an implausible .cmd
shim before reading it, and pruneOrphanedManagedHooks no longer prunes a
hook whose path is absolute on the other platform — existence is only
knowable for our own.
