🧹 refactor: Tighten Config Schema Typing and Remove Deprecated Fields (#12452)
* refactor: Remove deprecated and unused fields from endpoint schemas

- Remove summarize, summaryModel from endpointSchema and azureEndpointSchema
- Remove plugins from azureEndpointSchema
- Remove customOrder from endpointSchema and azureEndpointSchema
- Remove baseURL from all and agents endpoint schemas
- Type paramDefinitions with full SettingDefinition-based schema
- Clean up summarize/summaryModel references in initialize.ts and config.spec.ts

* refactor: Improve MCP transport schema typing

- Add defaults to transport type discriminators (stdio, websocket, sse)
- Type stderr field as IOType union instead of z.any()

* refactor: Add narrowed preset schema for model specs

- Create tModelSpecPresetSchema omitting system/DB/deprecated fields
- Update tModelSpecSchema to use the narrowed preset schema

* test: Add explicit type field to MCP test fixtures

Add transport type discriminator to test objects that construct
MCPOptions/ParsedServerConfig directly, required after type field
changed from optional to default in schema definitions.

* chore: Bump librechat-data-provider to 0.8.404

* refactor: Tighten z.record(z.any()) fields to precise value types

- Type headers fields as z.record(z.string()) in endpoint, assistant, and azure schemas
- Type addParams as z.record(z.union([z.string(), z.number(), z.boolean(), z.null()]))
- Type azure additionalHeaders as z.record(z.string())
- Type memory model_parameters as z.record(z.union([z.string(), z.number(), z.boolean()]))
- Type firecrawl changeTrackingOptions.schema as z.record(z.string())

* refactor: Type supportedMimeTypes schema as z.array(z.string())

Replace z.array(z.any()).refine() with z.array(z.string()) since config
input is always strings that get converted to RegExp via
convertStringsToRegex() after parsing. Destructure supportedMimeTypes
from spreads to avoid string[]/RegExp[] type mismatch.

* refactor: Tighten enum, role, and numeric constraint schemas

- Type engineSTT as enum ['openai', 'azureOpenAI']
- Type engineTTS as enum ['openai', 'azureOpenAI', 'elevenlabs', 'localai']
- Constrain playbackRate to 0.25–4 range
- Type titleMessageRole as enum ['system', 'user', 'assistant']
- Add int().nonnegative() to MCP timeout and firecrawl timeout

* chore: Bump librechat-data-provider to 0.8.405

* fix: Accept both string and RegExp in supportedMimeTypes schema

The schema must accept both string[] (config input) and RegExp[]
(post-merge runtime) since tests validate merged output against the
schema. Use z.union([z.string(), z.instanceof(RegExp)]) to handle both.

* refactor: Address review findings for schema tightening PR

- Revert changeTrackingOptions.schema to z.record(z.unknown()) (JSON Schema is nested, not flat strings)
- Remove dead contextStrategy code from BaseClient.js and cleanup.js
- Extract paramDefinitionSchema to named exported constant
- Add .int() constraint to columnSpan and columns
- Apply consistent .int().nonnegative() to initTimeout, sseReadTimeout, scraperTimeout
- Update stale stderr JSDoc to match actual accepted types
- Add comprehensive tests for paramDefinitionSchema, tModelSpecPresetSchema,
  endpointSchema deprecated field stripping, and azureEndpointSchema

* fix: Address second review pass findings

- Revert supportedMimeTypesSchema to z.array(z.string()) and remove
  as string[] casts — fix tests to not validate merged RegExp[] output
  against the config input schema
- Remove unused tModelSpecSchema import from test file
- Consolidate duplicate '../src/schemas' imports
- Add expiredAt coverage to tModelSpecPresetSchema test
- Assert plugins is absent in azureEndpointSchema test
- Add sync comments for engineSTT/engineTTS enum literals

* refactor: Omit preset-management fields from tModelSpecPresetSchema

Omit conversationId, presetId, title, defaultPreset, and order from the
model spec preset schema — these are preset-management fields that don't
belong in model spec configuration.
