fix(custom-model): address fourth pre-merge review + merge upstream master (Ark0N)

Merged upstream/master (22 commits: reboot-restore recovery feature,
terminal keycode229 recovery work, install.sh/CLI-catalog generator
changes, CHANGELOG/version bump to 1.30.0) into this branch. No
conflicts; git auto-merged every overlapping file (CLAUDE.md,
docs/api-reference.md, app.js, index.html, styles.css, routes/index.ts,
session-routes.ts, schemas.ts, server.ts).

Two required fixes from the latest review:

1. privilegedEnvKeys widening (stock.ts) changes behaviour outside this
   feature. The reviewer decided to keep both CLAUDE_CODE_MAX_CONTEXT_TOKENS
   and CLAUDE_CONFIG_DIR listed (types.ts's rule that every traffic-
   redirecting var this feature introduces must appear there stays
   literally true), and asked for the real consequences documented
   instead of hidden:
   - Corrected session-env-clamp.ts's fileoverview, which stated the
     opposite of what the code now does (reboot-restore's clamp call
     used to be able to strip nothing for claude; it now strips a
     persisted CLAUDE_CONFIG_DIR for a non-granted owner).
   - Corrected the rationale comments in stock.ts: privilegedEnvKeys
     has exactly one consumer (ownerClampedEnvKeys, feeding the
     generic envOverrides clamp on create/quick-start/reboot-restore),
     not the custom-model routes.
   - Added a CLAUDE.md line to the CLAUDE_CONFIG_DIR gotcha covering
     the admin-only-in-multi-user-mode and reboot-restore-strips-it
     consequences.
   - Added a "Claude multi-user clamp" test next to the existing
     DeepSeek/OMP ones, pinning the new stripping behaviour.

2. GET .../running-status (custom-model-routes.ts) no longer passes
   the raw llama-swap `cmd` field (the literal launch line, which can
   carry model paths and --api-key) to the browser -- the frontend
   only ever reads model/state, cmd exists solely for server-side
   parseCtxFromCmd() during discovery. Added a test asserting the
   response never contains cmd or a planted secret.

Also regenerated config/clis.stock.json and install.sh's catalogue
block (npm run generate:cli-catalog) to clear drift introduced by the
upstream merge, since it was failing the sync check.

Left to the reviewer, as they said they'd take at merge: the two
"comments pointing at removed code" cleanups, the two stale CLAUDE.md
counts, and the small items list (mode==='claude' frontend branch,
isCliAvailable() unknown-id gap, shared confirmed flag ordering,
one-shot cancel toast severity, pumpLlamaSwapLogTail buffer cap).
