Windows/Mac compatibility + surface all startup/execution errors in /bonsai:status

[ferdinandobons]

Summary

Two related goals: make the plugin run reliably on Windows and macOS (not just Linux), and make any startup or execution error visible from /bonsai:status.

The bash library was already carefully cross-platform aware (BSD-vs-GNU date/stat, shasum/sha256sum, mkdir mutex instead of flock, timeout/gtimeout fallback). The real gaps were: no line-ending protection for Windows checkouts, and no CI on anything but Linux — which is how an earlier release shipped a platform regression undetected.

Cross-platform

• .gitattributes — pins every text file to LF. On Windows, Git's default core.autocrlf=true rewrites the shell scripts to CRLF on checkout, which breaks bash (a CR in a shebang, or in a [[ "$x" == "$y" ]] compare) the moment a hook fires. git add --renormalize produced no churn — the tree is already LF.
• CI matrix — expanded from ubuntu-latest only to ubuntu-latest, macos-latest, windows-latest (Git Bash, shell: bash). shellcheck + unit tests run on all three; the timing-sensitive integration suite (detached background gardeners + polling) runs on the POSIX platforms. fail-fast: false so one red OS doesn't hide the others.

Errors in /bonsai:status (follow-up request)

Errors come from two independent places, and only the single last bonsai-errors.log line was previously shown:

• Hook failures (stop.sh, remind.sh — i.e. Stop/SessionStart/UserPromptSubmit) recorded in bonsai-errors.log by their ERR traps.
• Gardener subprocess failures that live in the per-run gardener-*.log result JSON and never reach bonsai-errors.log.

Changes:

• New bonsai_telemetry_gardener_errors helper — lists recent errored gardener runs with subtype + a flattened, truncated message, including unparseable/partial logs from a claude that died mid-write.
• status.sh now has an Errors section: 24h counts of hook errors and gardener errors, plus the most recent few lines of each with their messages.

Errors:
  hook errors (24h):    1
  gardener errors (24h): 1
  recent:
    hook: 2026-05-29T18:16:27Z [ERROR] stop.sh trap: line 42 (boom)
    gardener: 20260529T181627Z error_during_execution: model wedged

Docs

• README: new Requirements section (bash + jq; Windows via Git Bash) and updated Trust-posture bullet noting errors now surface in /bonsai:status.
• CHANGELOG entries under [Unreleased].

Tests

• test_telemetry.bats: coverage for bonsai_telemetry_gardener_errors (subtype+message listing, unparseable logs, cutoff + max-lines cap, empty/clean/missing-dir cases).
• test_commands.bats: status renders the Errors block clean, surfaces a recent hook error, and surfaces a gardener execution error.

Verification

bats isn't installable in this sandbox (network/sudo denied), so the new bash logic was validated directly: the telemetry helper and a full status.sh run were exercised end-to-end (both error and clean cases exit 0 under set -e), .gitattributes renormalization showed no churn, and the workflow YAML parses. The matrix CI on this PR is the real cross-platform check.
