roboomp a63da8a3a3 fix(coding-agent): made plugin install transaction atomic on validation failure
The #3063 fix introduced a second mutating step — `bun update <name>` —
that rewrites bun.lock before extension validation runs. Three failure
paths could still leave the rejected commit pinned in the lockfile or
active tree:

- Extension validation throwing after `bun update` had refreshed
  bun.lock — rollback restored package.json and node_modules/<name>
  but never touched bun.lock.
- Feature validation (`omp plugin install pkg[ghost]`) throwing
  outside the rollback block entirely.
- Runtime-config save failing after a successful install with no
  rollback path.

Snapshot bun.lock alongside package.json before `bun install` runs and
route every post-install step (resolution, update, package.json read,
feature validation, extension validation, runtime-config save) through
one outer catch that restores all three (package.json + bun.lock +
node_modules/<name> from snapshot). `#rollbackFailedInstall` now
tolerates an unresolved `actualName` for failures that throw before
the dep key is known.

Three regression tests in plugin-install-validation.test.ts pin the
new contract: bun.lock restoration after a git reinstall fails
validation, bun.lock removal when it didn't exist pre-install, and
rollback on an unknown feature request.

Addresses review feedback on #3069.
