When UpdateForm wraps fields that are already Option<T>, it creates
nested Options (Option<Option<T>>). The old bind_form_values method
bound these directly as &Option<T>, which caused MySQL "malform packet"
errors for Uuid -> BINARY(16) conversions.
Now both bind_form_values and bind_all_values use update_stmt_with_values()
which properly converts values through the Value enum:
- Some(None) -> Value::Null
- Some(Some(v)) -> Value::T(v)
This preserves the three-state semantics:
- None: don't include field in UPDATE
- Some(None): SET column = NULL
- Some(Some(v)): SET column = value

Usage:
User::update_by_filter(&pool, filters![("status", "pending")], form).await?;
- Requires at least one filter to prevent accidental table-wide updates
- Returns number of affected rows
- Binds form values first, then filter values

- Rename static-validation to static-check
- Fix upsert_stmt undefined when no database feature enabled
- Fix bind_all_values lifetime to use explicit 'q instead of '_
Decimal support requires enabling the 'decimal' feature flag.
Manual UpdateForm implementations need to add _exprs field.

- Add static_placeholder() function that uses $1 for postgres, ? for mysql/sqlite
- Restore static-validation feature with proper database-specific SQL
- cfg!(feature = "static-validation") now works correctly with query_as! macro

- Remove broken static-validation feature (hardcoded $1 placeholders)
- Add Value::Null variant for Option<T> support
- Add From<Option<T>> impl for all Value types
- Add f32, f64, NaiveTime, serde_json::Value support
- Add optional decimal feature for rust_decimal::Decimal
- All database backends now use runtime placeholder() function
Fixes issues:
- MySQL getting PostgreSQL $1 placeholders
- Missing From<Option<T>> implementations
- Missing base types (Decimal, JsonValue, NaiveTime, floats)

- Define version in workspace.package, inherit in all crates
- Rename MCP binary from sqlx-record-expert to sqlx-record-mcp
- Add clap for --version and --help support

- Add skill docs for batch ops, pagination, soft delete, transactions
- Update sqlx-entity.md with new attributes and methods
- Update sqlx-record.md with quick reference for all features
- Update MCP server with new feature documentation resources
- Fix .gitignore paths for renamed directories

New features:
- #[soft_delete] attribute with delete/restore/hard_delete methods
- #[created_at] auto-set on insert (milliseconds timestamp)
- #[updated_at] auto-set on every update (milliseconds timestamp)
- insert_many(&pool, &[entities]) for batch inserts
- upsert(&pool) / insert_or_update(&pool) for ON CONFLICT handling
- Page<T> struct with paginate() method for pagination
- find_partial() for selecting specific columns
- transaction! macro for ergonomic transaction handling
- PageRequest struct with offset/limit helpers
Technical changes:
- Added pagination.rs and transaction.rs modules
- Extended EntityField with is_soft_delete, is_created_at, is_updated_at
- Added generate_soft_delete_impl for delete/restore/hard_delete methods
- Upsert uses ON DUPLICATE KEY UPDATE (MySQL), ON CONFLICT DO UPDATE (Postgres/SQLite)
- Index hints supported in pagination and find_partial (MySQL)
All three database backends (MySQL, PostgreSQL, SQLite) tested and working.

New features:
- UpdateExpr: Advanced updates with column arithmetic (Add, Sub, Mul, Div, Mod),
CASE/WHEN conditionals, AddIf/SubIf, Coalesce, Greatest, Least, and raw SQL
- ConnProvider: Flexible borrowed/owned connection management
- lookup_table! and lookup_options! macros for type-safe lookup tables
- new_uuid() for time-ordered UUIDs with better database indexing
- MCP server (sqlx-record-expert) with documentation tools and resources
- Claude Code skills for all features
Improvements:
- Fixed Postgres/SQLite unsigned integer binding (cast to signed)
- Added From implementations for all integer types to Value
- Added param_count() to Filter for expression parameter counting
- Added bind_all_values() for proper expression binding order
All three database backends (MySQL, PostgreSQL, SQLite) build and work correctly.
