chore: bump to v0.1.39

[claude]

Requested by Alex Kroman · Slack thread

What & why

Version bump to 0.1.39 (CFBundleShortVersionString 0.1.38 → 0.1.39, CFBundleVersion 38 → 39). Generated by the release-bump workflow — run 31641116076, started from a pushed marker branch at main's tip.

Merging this starts the release: the changed version landing on main triggers release.yml, which builds, signs, and notarizes the DMG, then parks on the release-publish approval gate before anything ships.

How it was tested

• scripts/check.sh passes (or CI will, if I'm not on a Mac) — generated bump only; the check workflow runs on this PR
• I read AGENTS.md and this doesn't reintroduce anything deliberately removed
• Docs updated if behavior changed — n/a, generated bump only

Dev build

Download Blurt.app — built from 5e79c16, Debug-Local,
ad-hoc signed. Expires in 14 days.

Installing it

cd ~/Downloads
unzip -o blurt-dev-build-pr-131.zip   # GitHub wraps every artifact in a zip
unzip -o Blurt-dev-5e79c16.zip
find Blurt.app -exec xattr -c {} +   # clear quarantine: xattr lost -r in macOS 12.3
rm -rf /Applications/Blurt.app && cp -R Blurt.app /Applications/
open -a Blurt

It is ad-hoc signed and not notarized: Gatekeeper refuses to open it until
the quarantine flag is cleared, and macOS treats it as a different app from a
released Blurt, so you have to re-grant Microphone, Accessibility, and Input
Monitoring. Reinstall the release DMG
when you are done reviewing.

Expect that re-grant once per dev build, including a second build of this
same PR. TCC pins an Accessibility grant to the signature that took it, and an
ad-hoc signature is just a hash of the binary, so every build is a new app as far
as tccd is concerned. Blurt clears the orphaned grant at launch, which is what
keeps the Accessibility step from getting stuck on a Blurt row that is switched on
and still denied. If you are coming from a build old enough to predate that,
clear the grant yourself once:

tccutil reset Accessibility dev.alex.blurt
