feat(autocorrect): add fuzzy subcommand matching and flag-as-subcommand detection

Extend the CLI autocorrection pipeline with two new correction rules that
help agents recover from common typos and misunderstandings:

1. SubcommandFuzzy (threshold 0.85): Fuzzy-matches typo'd subcommands
   against the canonical list. Examples:
   - "issuess" → "issues"
   - "timline" → "timeline"
   - "serach" → "search"
   
   Guards prevent false positives:
   - Words that look like misplaced global flags are skipped
   - Valid command prefixes are left to clap's infer_subcommands

2. FlagAsSubcommand: Detects when agents type subcommands as flags.
   Some agents (especially Codex) assume `--robot-docs` is a flag rather
   than a subcommand. This rule converts:
   - "--robot-docs" → "robot-docs"
   - "--generate-docs" → "generate-docs"

Also improves error messages in main.rs:
- MissingRequiredArgument: Contextual example based on detected subcommand
- MissingSubcommand: Lists common commands
- TooFewValues/TooManyValues: Command-specific help hints

Added CANONICAL_SUBCOMMANDS constant enumerating all valid subcommands
(including hidden ones) for fuzzy matching. This ensures agents that know
about hidden commands still get typo correction.
