feat: add builtin types/functions to diagnostics and completions

Browse Source 
Files Modified/Created:
- src/builtin_instructions.lua - NEW: Contains all TIA Portal built-in types, FBs, and functions
- src/diagnostics.lua - Added missing data types + builtin instruction checking
- src/main.lua - Added completion support for built-in types/F Bs/functions
- src/plc_json.lua - Added .db file parsing + BOM handling fixes
- lua/scl/blink_cmp_source.lua - Extended completion with all built-in types/F Bs/functions
- src/node-types.json - Added node types for parser
- AGENTS.md - Updated documentation
Features Added:
1. Diagnostics - No more false "Unknown data type" warnings for:
   - All elementary types (USINT, SINT, UINT, UDINT, LINT, ULINT, TOD, DTL, etc.)
   - Timer/counter types (IEC_TON, TOF, TP, CTU, CTD, CTUD)
   - TIA Portal built-in FBs and functions
2. Auto-completion - Shows in VAR section after ::
   - 28 elementary data types
   - 23 built-in function blocks (TON, TOF, TP, CTU, CTD, CTUD, R_TRIG, F_TRIG, etc.)
   - 80+ built-in functions (ADD, SUB, MUL, DIV, SIN, COS, SQRT, etc.)

## Diagnostics
The LSP validates data types and provides warnings for unknown types. It recognizes:
- **Elementary data types** - BOOL, BYTE, WORD, DWORD, LWORD, CHAR, WCHAR, STRING, WSTRING, INT, DINT, LINT, USINT, SINT, UINT, UDINT, ULINT, REAL, LREAL, TIME, DATE, TOD, TIME_OF_DAY, DATE_AND_TIME, DT, S5TIME, LTIME, DTL
- **Timer/counter types** - IEC_TIMER, TON_TIME, TOF_TIME, TONR_TIME, TP_TIME, CTU, CTD, CTUD
- **TIA Portal built-in instructions** - Functions and function blocks
- **Workspace types** - UDTs from `.udt` files and data blocks from `.db` files
## Completion Triggers
- `#` - Local variables (after BEGIN)
- `.` - Member access (UDT/DB)
- `"` - Global DB names
- `(` - FB/Function parameters
- ` ` (space) - General completion
- `:` - Type declaration (in VAR section)
### Completion Types
The LSP provides auto-completion for:
- **Local variables** - Variables declared in VAR sections
- **UDT types** - User-defined types from `.udt` files
- **Global DBs** - Data blocks from `.db` files
- **Elementary types** - BOOL, INT, DINT, REAL, TIME, etc.
- **TIA Portal built-in FBs** - TON, TOF, TP, CTU, CTD, CTUD, R_TRIG, etc.
- **TIA Portal built-in functions** - ADD, SUB, MUL, DIV, SIN, COS, SQRT, etc.
