FastEdit 0.2.6

Added

• PyPI version check with MCP-aware surfacing. On the first successful fast_edit / fast_batch_edit call in an MCP server session, if a newer release exists on PyPI, the tool response gets a one-line banner appended so the host LLM can relay the notice to the human who actually owns the environment. The model can't pip install, so the notice targets the user through the model's next turn. Subsequent calls in the same session are silent. CLI runs get a stderr notice on exit. Checks cache for 24 h in ~/.cache/fastedit/update-check.json. Silent when up-to-date, on network failure, or when FASTEDIT_NO_UPDATE_CHECK=1 is set. Uses stdlib urllib — no new dependencies.

Changed

• MCP tool instructions rewritten around minimal-payload patterns. The fast_edit tool description and the top-level FastMCP instructions now lead with the six use-case patterns (add-guard / append / middle / full-replace / after / preserve_siblings) paired with the minimal snippet shape for each. The marker-position semantics (top/bottom/middle insert) and short marker forms (#... / //... / …) shipped in 0.2.4 are now surfaced to every LLM that picks up the tool, not buried in the changelog. Signature auto-preserve (0.2.2) is stated explicitly: replace='name' carries the def/fn/class line, so the snippet should omit it.
• README teaser updated to use the minimal form — short #... marker, no signature line. Shows what the calling agent actually writes today, not the 0.2.0 long form.

No breaking changes — all existing payloads keep working.
