Second review pass on #282, the three items left open after f4dcfbe.
1. `codeman doctor` and the run mode disagreed about pi. The registry entry
accepted a bare `which pi` hit while pi-cli-resolver demanded semver-shaped
`--version` output, so the Dependencies panel could report an installed Pi CLI
on a box where Run Pi stays hidden, which reads as a broken mode rather than a
missing install. Both sides now share one exported PI_VERSION_REGEX, and
PathResolver gains an opt-in `requireVersionMatch` so a binary that fails the
shape check is reported MISSING instead of installed-with-unknown-version.
Only pi sets it; every other tool keeps its current behaviour.
2. The isAltScreenStripMode comment justified excluding pi with "the alt screen
is load-bearing for its fullscreen TUI". That is not what exclusion does: pi
is tmux-backed, so it falls through to isMuxAltScreenOnlyStripMode, which
strips the alt-screen toggles anyway. What exclusion actually preserves is
`\x1b[3J` and the mouse DECSETs, which is the real reason (pi renders into the
main screen and is mouse-aware). Comment and changeset now say that, and state
the consequence: fullscreen pi paints into the main buffer, like vim in a tmux
shell session.
3. skills/codeman still enumerated the five pre-pi modes in nine places, telling
agents a backend does not exist and understating class-wide caveats by one
mode. All updated, plus stale session.ts line references refreshed.
Tests: a new static guard derives the mode set from the Zod schema (not a copy)
and fails when a skill enumeration lists a partial set of external CLIs, verified
by mutation. It also documents the one legitimate exception it found: the "writes
no transcript" lists drop codex, which does write a rollout Codeman reads back.
Plus doctor cases for an unrelated `pi` on PATH and registry/resolver regex parity.

Environment-aware dependency probe (linux|darwin|win32|wsl) with a static
registry, an injectable ProbeHost seam for testing, grouped table + `--json`
output, and a non-zero exit when a required dependency is missing/outdated.
Node and tmux are the only hard-required tools; the agent CLIs and document
converters (LibreOffice / MS Office via WSL interop) are optional. CI-safe
unit tests (no tmux, injected host).
