fix: revert mosaic to 0.0.22 alpha + republish macp

Two errors shipped in #419 (mosaic-v0.1.0 release):

1. Version policy violation — @mosaicstack/mosaic was bumped 0.0.21 →
   0.1.0, jumping out of 0.0.x alpha without authorization. The project
   stays in 0.0.x until GA. Revert to 0.0.22.

2. @mosaicstack/macp exports fix never reached the registry. PR #415
   fixed packages/macp/package.json exports.default (was pointing at
   ./src/index.ts, broke installed consumers with ERR_MODULE_NOT_FOUND),
   but did not bump macp's version. The post-merge publish workflow
   silently skipped macp@0.0.2 as "already published", leaving the bad
   copy on the registry. Installing mosaic@0.1.0 resolves macp@0.0.2
   from the registry and crashes on startup. Bump macp 0.0.2 → 0.0.3 to
   force republish with the correct exports map.

Follow-up cleanup after merge:
- delete git tag mosaic-v0.1.0 + Gitea release
- delete @mosaicstack/mosaic@0.1.0 from Gitea npm registry so `latest`
  reverts to the highest remaining version
- create new tag mosaic-v0.0.22 + Gitea release

+### Wave 6 — M8 correction (version regression)
+
+PR #419 bumped `@mosaicstack/mosaic` 0.0.21 → 0.1.0 and released as `mosaic-v0.1.0`. This was wrong on two counts:
+
+1. **Versioning policy violation.** The project stays in `0.0.x` alpha until GA. Minor bump to `0.1.0` jumped out of alpha without authorization.
+2. **macp exports fix never reached the registry.** PR #415 fixed `packages/macp/package.json` `exports.default` pointing at `./src/index.ts`, but did NOT bump macp's version. When the post-merge publish workflow ran on #419, it published `@mosaicstack/mosaic@0.1.0` but `@mosaicstack/macp@0.0.2` was "already published" so the fix was silently skipped. Result: users running `mosaic update` got mosaic 0.1.0 which depends on macp and resolves to the still-broken registry copy of macp@0.0.2, failing with `ERR_MODULE_NOT_FOUND` on `./src/index.ts` at CLI startup.

+Correction PR:
+
+- `@mosaicstack/mosaic` 0.1.0 → `0.0.22` (stay in alpha)
+- `@mosaicstack/macp` 0.0.2 → `0.0.3` (force republish with the exports fix)
+- Delete Gitea tag `mosaic-v0.1.0` + release
+- Delete `@mosaicstack/mosaic@0.1.0` from the Gitea npm registry so `latest` reverts to the highest remaining version
+- Create tag `mosaic-v0.0.22` + Gitea release
+
+**Lesson captured:** every package whose _source_ changes must also have its _version_ bumped, because the publish workflow silently skips "already published" versions. `@mosaicstack/macp@0.0.2` had the bad exports in the registry from day one; the in-repo fix in #415 was invisible to installed-from-registry consumers until the version bumped.

 ### Mission outcome
 
-All 8 milestones, all 8 success criteria, merged to main, green CI on every PR, released. Two sessions total (~10h combined). No rollbacks, no blocked milestones, no escalations required.
+All 8 milestones, all 8 success criteria met in-repo. Released as `mosaic-v0.0.22` (alpha) after correcting an incorrect 0.1.0 version bump + missed macp republish. Two sessions total (~10h combined) plus a follow-up correction PR.
