chore: finish the move to the bitbaum org, and make verify honest again

[catomean]

Two small things, both about the repo telling the truth.

The org moved but the links did not

cd61f82 pointed the deploy workflow at bitbaum/fleetcrown and stopped there. Every other reference still said catomean:

• the View source on GitHub links on /about and /security
• the three URLs behind them in src/lib/config/ecosystem.ts (Solon, OrangeCat, FleetCrown)
• the clone command in the README
• the @fleet/design-tokens git dependency in package.json + lockfile
• the incident notes in scripts/ci/auto-merge-sweep.sh

Nothing is broken today only because GitHub 301-redirects a renamed org — verified: catomean/solon → bitbaum/solon, catomean/design-tokens → bitbaum/design-tokens. That redirect disappears the moment anyone claims the catomean name, and it is not something to hang dependency resolution on. npm ci resolves the new URL at the same commit sha, so lockfile integrity is unchanged — checked with a clean npm ci.

npm run verify failed on files CI never sees

The gate's promise is green locally ⇒ green in CI. It was not holding, in the worse direction: locally red, CI green.

• The harness checks this repo out a second time under .claude/worktrees/<branch>/ for concurrent sessions. Git treats it as a separate worktree; prettier, eslint and tsc read it as ordinary files. prettier --check . failed on 88 files belonging to a different branch, and tsc was compiling that branch's code into this branch's verdict.
• .claude/settings.local.json is per-machine agent config, ignored only by the developer's global gitignore, so prettier checked a file the repo does not own.

Both are now out of scope for all three tools, and both are ignored by this repo rather than by whatever happens to be in ~/.config/git.

Verification

npm run verify after a clean npm ci + prisma generate:

format:check  ok
lint          ok
typecheck     ok
design:check  ok
test          9 passed | 3 skipped (12 files) · 82 passed | 10 skipped (92 tests)
