v0.5.0 — company starter packs

What's new

• /companies → "Add a starter pack": curated segments of companies, each board re-probed live before anything is written
• 86 companies across 5 segments (PHP/Laravel & CMS, JS infra & dev tools, JS/TS product & headless CMS, remote-first, UA-friendly remote)
• Preview before insert: new boards, boards already tracked, and unresolved names with a reason — a name is never dropped silently
• Companies land disabled, with an "Enable all" button after the import; re-importing a pack adds nothing
• ATS probe failures now say what actually happened — rate limiting and vendor outages no longer report "token likely invalid"

Schema

• no schema changes

Verification

• 500 unit tests green; live probe smoke on the PHP (23) and UA (11) segments; full UI round-trip in Docker incl. re-import and rejected picks; screenshots 1200/375, 0 console errors
