No-op validation release (pure version bump, zero code changes vs deployed 0.1.122).

Diff vs released v0.1.122 = this version bump only (master's only other change since the tag is README docs).

Why a no-op (AGENTS.md §5 auto-update rule)

Two stacked, not-yet-validated changes to the auto-update path are pending:

1. [dsh] unify install lanes: bili plugin install dsh should go through the bundle channel + auto-update rewrite #966 (already shipped inside 0.1.122, without the no-op flow): src/update.ts gained the refreshDshProfileBundles hook on self-update — 6 lines that have never executed a real-world upgrade: the 0.1.121 → 0.1.122 hop this morning was performed by 0.1.121's code.
2. fix: single-writer plugin guard — never overwrite host-managed copies (#991) #995 (single-writer plugin guard, still open): changes checkForUpdate/installViaTarball decision logic.

Per AGENTS.md §5, updater changes must be preceded by a no-op release proving the existing upgrade path. The next hop (0.1.122 → 0.1.123) will be executed by 0.1.122's updater — validating #966's hook and the plumbing — using code we already trust, independent of #995.

Validation plan

1. Merge this PR → CI publishes 0.1.123.
2. A local bili process running 0.1.122 (already in place) auto-updates; log must show [update] installed 0.1.122 → 0.1.123. Restart to finish.
3. Only then merge fix: single-writer plugin guard — never overwrite host-managed copies (#991) #995 and release 0.1.124 normally.
