docs: record the getter fix result and why JS/TS retrieval misses

[bompus]

Adds two paragraphs to the gap register in the survey doc.

• Section 6.1: the measured result of fix(resolve): type TypeScript getters and stop plain constructor parameters standing in for fields #450 on hono (469 to 472 of 706 oracle edges; 74 edges added, none removed). The earlier estimate of up to 3 points was too high, and the doc says why.
• Section 6.2: what the 19 zero-coverage JavaScript and TypeScript instances show. The needed files are indexed, an identifier-only query adds 4 of 58 files, and one report quotes text found verbatim in a needed file.

Docs only. The numbers are from the runs described in #450 and a re-fetch of the 19 base trees.

Summary by CodeRabbit

• Documentation
  • Added compiler-oracle results showing 74 additional call edges for Hono, matching three more oracle edges; Zod results were unchanged.
  • Expanded retrieval findings: most missed JavaScript and TypeScript files were indexed, identifier-based queries recovered few misses, and a verbatim-text example was not returned by codegraph explore.

Before / after behavior

• observed — Modified behavior in docs/design/competitive-landscape-adoption.md: The replay reports PR #450’s getter-property typing change: it adds 74 hono call edges and no removals, leaves zod’s edges unchanged, and increases hono oracle matches from 469 to 472 of 706. It notes that 63 added edges are in unjudged test files, eight have callers the oracle did not reach, and three match a different overload line; overload normalization is unmeasured.
• observed — Modified behavior in docs/design/competitive-landscape-adoption.md: The retrieval analysis reports that 54 of the 58 needed files in the 19 missed instances are indexed, while queries using up to 10 report identifiers find only four. It gives one exact-text miss and explains that the index covers names, docstrings, and signatures, with only short strings indexed; the passage characterizes the misses as limited overlap between symptom descriptions and compiler-file names.

the four needed files absent from the fork’s index cannot be returned by
queries, and say indexing is not the main cause only if supported by the
figures. Keep the distinction between this limitation and the broader retrieval

Fixed: the paragraph now says the four unindexed files cannot be returned, and that indexing is not the main cause because the other 54 are indexed and still missed.
