fix(react-doctor): fix 3 bugs, resolve AGENTS.md violations, upgrade oxc

Bugs fixed:
- tanstackStartRedirectInTryCatch: was using node.parent which oxlint JS
  plugins don't populate — rule never fired. Rewrote to use ThrowStatement
  visitor with tryCatchDepth tracking (matches existing nextjs pattern)
- tanstackStartServerFnValidateInput: fragile chain-walking logic with
  potential infinite loop. Extracted shared walkServerFnChain() helper,
  removed unused serverFnChains variable
- tanstackStartNoNavigateInRender: componentDepth never decremented for
  arrow components (no VariableDeclarator:exit), eventHandlerDepth was
  declared but never modified. Removed dead variable, simplified

AGENTS.md violations fixed:
- Removed unused hasDirective import
- Moved SEQUENTIAL_AWAIT_THRESHOLD_FOR_LOADER to constants.ts
- Moved TANSTACK_REDIRECT_FUNCTIONS to constants.ts
- Moved TANSTACK_SERVER_FN_FILE_PATTERN to constants.ts
- Replaced inline /^[A-Z]/ with existing UPPERCASE_PATTERN constant
- Replaced duplicate MUTATION_CALLEE_NAMES with existing MUTATION_METHOD_NAMES
- Removed 'as string' type cast, replaced with typeof guard

Upgraded oxc:
- oxlint: 1.59.0 → 1.60.0
- oxfmt: 0.44.0 → 0.45.0
