Core and desktop comments describe the code to a stranger (#6224)

Milestone 546 "Bring the repo to the comment standard (rule 32) and
compose defaults (rule 198)", step #6224 "Comment standard sweep: Rust
core and desktop client".

Doc comments and comments across inkwell-core, the Tauri app and
desktop/packaging now say what the code does and the non-obvious why in
the present tense. Gone: milestone tags (M10.x, M11.3, M13, M304, M315,
M314, milestone 325), issue and Scribe-note numbers, family-idea and
family-rule citations, the run numbers and commit hashes behind past
bugs, and the narration of what used to be (the stable channel before it
held its own bundles, CARGO_PKG_VERSION as the shown version, the
MANIFEST_TAG split, the store's missing tests, the old PKGBUILD). The
schema's migration notes keep what each step does and why, without
"until now". The forge is called the forge rather than Forgejo.

Hazards stay as facts: the dev-rolling tag that must not shadow the
branch, the manifest matched on this build's version, the APK's fixed
name surviving the prune, the LIKE guard in v9, -wal/-shm moving with
the renamed store, panic = abort ending the app.

34 files, comments only: a comment-stripping diff of every changed file
against HEAD is identical.
