improvement(lint): strip comment noise and add check:comment-hygiene (#8551)

* chore(lint): delete commented-out code

Removes dead sub-block configs from the Human in the Loop and Greptile
blocks and an unused commented-out DisplayMode type. The docs generator
read the commented-out greptile_search entry in tools.access, so the
generated Greptile docs advertised a disabled operation; regenerated.

* improvement(audits): add check:comment-hygiene

Fails on banner separator comments and on line comments whose text
parses as TypeScript (commented-out code). Comments come from the Babel
token stream so strings are never inspected; prose lines split comment
groups, and labels, literals and one-off glosses are rejected, giving
zero false positives across the tree. Change-history phrasing was
measured and left out because most hits describe live state.

* chore(lint): remove banner separators and narrating comments

Converts decorated section banners to plain comments or drops them, and
sweeps the noisiest files for comments that restate the code or name
what follows. Field-level notes that carry units, enums or invariants
move to TSDoc. Comment-only: the non-comment token stream of every
changed file is identical.

* fix(audits): fail comment-hygiene on unparsable files, raise listing buffer, correct ribbon arc note

-Search repositories in natural language and get relevant code references without generating an answer. Useful for finding specific code locations.
-
-#### Input
-
-| Parameter | Type | Required | Description |
-| --------- | ---- | -------- | ----------- |
-| `query` | string | Yes | Natural language search query to find relevant code. Example: "authentication middleware" or "database connection handling" |
-| `repositories` | string | Yes | Comma-separated list of repositories. Format: "github:branch:owner/repo" or just "owner/repo" \(defaults to github:main\). Example: "facebook/react" or "github:main:facebook/react,github:main:facebook/relay" |
-| `sessionId` | string | No | Session ID for conversation continuity. Use the same sessionId across multiple searches to maintain context. Example: "session-abc123" |
-| `genius` | boolean | No | Enable genius mode for more thorough search \(slower but more accurate\) |
-| `apiKey` | string | Yes | Greptile API key |
-| `githubToken` | string | Yes | GitHub Personal Access Token with repo read access |

 ### Greptile Index Repository
 
 Submit a repository to be indexed by Greptile. Indexing must complete before the repository can be queried. Small repos take 3-5 minutes, larger ones can take over an hour.
