Add SQLite as the seventh supported dialect

[oyvindberg]

Summary

• Adds SQLite (org.xerial:sqlite-jdbc:3.49.1.0) as the seventh dialect alongside PostgreSQL, MariaDB, DuckDB, Oracle, SQL Server, and DB2. New SqliteType / SqliteTypes / SqliteConfig plus Kotlin and Scala wrappers, full docs page and snippets, and an SqliteTypeTest that exercises every type in every "position" SQLite supports (column read/write, WHERE-parameter, NULL via opt(), non-null via opt(), query analysis, query analysis with bound parameter — there are no others, since SQLite has no nested types).
• Fixes a latent SingleConnection.transactor() routing bug uncovered by SQLite's :memory: tests: the wrapper delegated to underlying.transactor(), which built the transactor against the unwrapped SimpleDataSource and bypassed the singleton-connection proxy. Each transact() then opened a fresh in-memory database. Affects DuckDB :memory: too — masked because DuckDbTypeTest poked raw JDBC instead of going through the transactor. Added transactorEndToEnd() smoke tests to both SqliteTypeTest and DuckDbTypeTest so future regressions of this shape fail loudly.
• Fixes a QueryAnalysis reporting bug: PrepareFailure was added to allErrors() for the ✗ summary indicator but never rendered in the report body, so users saw a ✗ with no driver message or hint. Now emitted before the parameters/columns tables.

Three commits

1. feat(sqlite): add SQLite dialect support — core dialect (SqliteType/Read/Write/Json/Types/Typename/Config), Kotlin & Scala wrappers, DatabaseKind.SQLITE, OTel DatabaseSystem.SQLITE, build wiring, full type-roundtrip test
2. docs(sqlite): add SQLite docs page, snippets, and analyzer matrix updates — site/docs/sqlite.md, 36 snippet files (12 sections × 3 languages), landing page (Six → Seven databases), sidebar, database-types.md, stored-procedures.md, and the four analyzer-behavior matrices in query-analysis-database-behavior.md (backed by direct probes of the xerial driver, not guesses)
3. fix: SingleConnection routing + PrepareFailure rendering, end-to-end tests — the two bug fixes above plus three pre-existing QueryAnalysisTest assertion updates that referenced the old report format

SQLite-specific design notes

• STRICT tables recommended. A non-strict SQLite table accepts any storage class regardless of declared type. The docs spell this out and the transactorEndToEnd test creates a STRICT table.
• Date/time pinned to text. SqliteTypes.date/.time/.datetime/.timestamp/.instant all read and write ISO-8601 TEXT, matching the xerial driver's default date_class=TEXT. Sub-millisecond precision is silently truncated by LocalDateTime writes; Instant round-trips at full nanosecond precision because Instant.toString() does.
• BigDecimal stored as TEXT. The xerial driver's setBigDecimal/getBigDecimal throw column -1 out of bounds; storing as plain text via setString/getString + BigDecimal::toPlainString round-trips and preserves arbitrary precision (a side benefit, since SQLite has no enforced precision either way).
• No procedures, no arrays, no structs, no maps. SqliteType.outParam() returns Optional.empty(). The docs page enumerates the absent features.
• Affinity-based vendor aliases for query analysis. Each type registers the alternate spellings SQLite recognises — e.g. SqliteTypes.integer accepts INTEGER, INT, INT2, INT4, INT8, BIGINT, SMALLINT, TINYINT, MEDIUMINT, UNSIGNED BIG INT so CREATE TABLE t (x BIGINT) analyses cleanly.

Test plan

• bleep compile foundations-jdbc foundations-jdbc-hikari foundations-jdbc-spring foundations-jdbc-kotlin foundations-jdbc-scala — clean
• bleep test foundations-jdbc-test -o dev.typr.foundations.SqliteTypeTest — 2 passed (matrix + transactor end-to-end)
• bleep test foundations-jdbc-test -o dev.typr.foundations.DuckDbTypeTest — 4 passed (now includes transactor end-to-end)
• bleep test foundations-jdbc-test -o dev.typr.foundations.QueryAnalysisTest — 70 passed (was 67 + 3 failing pre-existing)
• All 125 embedded tests across SQLite + DuckDB + analyzer + parser suites pass together
• npm run build in site/ — Docusaurus build clean, /docs/sqlite/index.html rendered, all 36 snippets resolved
