* fix(ai-vault): stop a whole opencode.db failure reading as one skipped transcript #15036 reported "1 transcript skipped / database is locked" with both Agent Session History scopes empty. Two separate defects. The panel counts every unkinded scan issue as a skipped transcript, so a failure that lost an entire *source* was reported as one lost *file*. The whole-database failure is now kinded `scope`, and an unknown `kind` from a newer host degrades to `scope` instead of failing validation and coming back unkinded — a mixed-version remote host previously turned a source-level failure into a phantom skipped transcript. The read also inherited sqlite3's 0 ms busy timeout, so a genuinely contended open failed in ~1 ms. It now opens once with a bounded timeout. No retry loop: sqlite's own busy handler already blocks and retries internally for the whole timeout, and WAL readers do not block on a writer at all (measured: 547/547 cross-process reads at timeout=0 while a writer held open transactions). Measured against a real Ubuntu-24.04 distro, Windows cannot take SQLite's file locks over \\wsl.localhost at all: an idle, never-WAL, nothing-attached database still answers SQLITE_BUSY, a 5 s busy timeout does not change it, and the identical bytes open fine once copied to local disk. So a lock-family error on that share never means "a writer holds it" and no timeout can help. The copy says so rather than sending the user after a write-ahead log that is not the problem. Restoring those sessions needs an in-distro read; that is a follow-up, and this PR no longer pretends a timeout will do it. immutable=1 is deliberately not used as a workaround: over the same share it opens and returns 100 of 150 rows, silently dropping everything still in the uncheckpointed -wal — in a history panel, exactly the newest sessions. * skip the provably futile busy wait on \\wsl.localhost paths
