v0.6.1

Patch release: token-savings tuning, output-cache DRY refactor, and stat-accounting fixes.

Changed

• Token-savings tuning across the hint, compaction, and output surfaces. Three internal improvement sweeps tightened the text Token-Goat injects into the conversation: shorter session read-hints and bash / grep / web dedup hints, leaner PreCompact manifest framing, a more compact post-compaction recovery hint, terser token-goat map output framing, and budgeted git-history and project-memory injections. The CLAUDE.md / SKILL.md / AGENTS.md directive blocks written by token-goat install were condensed without dropping any guidance. The result is the same hints for fewer tokens.
• Command --json output is now compact single-line JSON. stats, map, config, bash-output, web-output, bash-history, web-history, compact-hint, and the surgical-read commands emit --json with no indentation whitespace. JSON written to disk (settings.json and config files) stays pretty-printed for human editing.
• bash-output and web-output recall now default to a smart head-and-tail view for large cached outputs, with --full to retrieve the whole thing.
• DRY pass on the output-cache layer. bash_cache and web_cache were near-parallel implementations; their shared pieces (the cache-filename pattern, session-id sanitization, JSON-sidecar loading, and LRU disk-cap eviction) now live in one cache_common module. No user-visible behavior change. Regression tests were added across the token-savings, stat-accounting, and cache surfaces.

Fixed

• compact_recovery stat accounting. The post-compaction recovery hint recorded no injection overhead and was bucketed under the other source instead of compact. It now records a compact_recovery_overhead row consistent with the session_hint, diff_hint, and bash_dedup_hint siblings, and both compact_recovery kinds map to the compact source bucket.
• bash-output and web-output recalls were credited no savings. Retrieving a cached output instead of re-running a command, or a cached response instead of re-fetching a URL, now records a bash_output_recall or web_output_recall stat. This closes a measurement gap where thousands of cache hits showed zero tokens saved.
