v1.92.69.0 fix: lock developer-profile writers so overlapping derives keep every session (#3437, #3435) (#3738)

* fix(plan-tune): lock developer-profile writes and give derive a unique temp file (#3437)

Concurrent background --derive runs shared developer-profile.json.tmp and rewrote the whole profile unlocked, so renames failed with ENOENT and a concurrent --log-session was dropped. Every read-modify-write now holds developer-profile.json.lock and writes a mktemp file.

* chore(plan-tune): remove applySignal and newDimensionTotals (#3435)

Both lost their last production caller when --derive moved onto accumulateSignals; only three unit tests referenced them.

* fix: pre-landing review fixes

Use the PID in the lock token, anchor a relative state root once so do_derive's cd cannot leak the lock, and note the stale-takeover tradeoff.

* fix: pre-landing review fixes (pass 2)

Keep Windows drive-letter state roots absolute when anchoring a relative root, and say which writers do not take the lock yet.

* fix: take over a lock only from a dead holder, one taker at a time

Step 11 voices: a late stale-lock mv could evict a fresh owner, a failed mv spun past the timeout, and the 10 s give-up sat under the 30 s stale age. Takeover now checks the holder's pid, re-reads the owner under a takeover lock, falls through to the give-up on failure, and reports an unwritable state directory at once.

* fix: take over an owned lock older than 5 minutes (pid reuse)

A crashed holder whose pid now belongs to a live process kept its lock forever. An owned lock past 5 minutes now counts as abandoned, and cleanup removes a takeover lock this writer holds.

* test: keep the give-up test inside the type ratchet
