fix(skill): write --plan / --competitors-plan to tmpfile, bump 3.2.2 -> 3.2.3

Browse Source 
Closes #403.

The SKILL.md templates instructed the model to invoke the engine with
inline single-quoted JSON: `--plan '$JSON'` and `--competitors-plan '{...}'`.
When any resolved field value contained an apostrophe (common in `context`
strings like "McDonald's", "people's choice", or contracted forms like
"don't", "won't"), the inner `'` closed the outer single-quote and broke
shell parsing before the engine was even invoked.

Observed during PR #400 testing: a Codex run hit the trap and self-healed
by re-encoding, wasting one engine invocation and ~30s of latency.

Fix: switch both templates to the heredoc + tmpfile pattern. The engine's
`parse_plan()` and `parse_competitors_plan()` already check
`os.path.isfile(plan_str)` and read from disk — only the SKILL.md prose
needed to change.

The quoted heredoc marker (<<'PLAN_EOF') is load-bearing: it suppresses
shell interpolation so apostrophes, $, backticks, etc. pass through verbatim.
A trap on EXIT cleans up the tmpfile after the engine call returns.

LAW 7's "MUST contain --plan" self-check guidance and Step 1's invocation
example both updated to reference the file form. Comparison-mode invocation
block updated the same way for --competitors-plan.

Version bump 3.2.2 -> 3.2.3 because this is a behavior change users
running comparison-mode queries will notice (no more "shell quoting error,
retrying" sequences on apostrophe-containing context strings).

- Bump `POSTS_PER_CLUSTER` from 3 to 5 and the render-side display limit from 2 to 3 to match the per-source enrichment caps used by Reddit, HN, YouTube, TikTok, and GitHub. The previous 3/2 caps routinely truncated cluster context (e.g. dropped a Jason Calacanis quote tweet on a `cli-printing-press` run).
- Rewrite SKILL.md path resolution. STEP 0 narrows from a global canonical-path enforcement to a Claude-Code-marketplaces-only stale-clone guard. Step 1 SKILL_ROOT resolver walks a single precedence list (Claude plugin cache, then `~/.codex/skills/`, `~/.agents/skills/`, repo checkout, `./.skills/last30days` for `npx skills add`, CWD, Gemini). Adds SKILL.md frontmatter fallback to `render.py::_skill_version` so the badge no longer prints `v?` on installs that don't include `.claude-plugin/plugin.json`.
- Switch SKILL.md's `--plan` and `--competitors-plan` invocation templates from inline single-quoted JSON to heredoc-written tmpfiles. Apostrophes in resolved context strings ("McDonald's", "people's choice", "developer's") previously closed the outer single-quote and broke shell parsing before the engine started — observed in a Codex run during PR #400 testing. The engine's `parse_plan()` / `parse_competitors_plan()` already supported file paths (via `os.path.isfile()` probe); only the template prose changed. Fixes [#403](https://github.com/mvanhorn/last30days-skill/issues/403).
### Removed
- **BREAKING for Codex native-plugin users:** `.codex-plugin/plugin.json` and the matching SKILL_ROOT resolver branch in SKILL.md Step 1. Codex users should install via `npx skills add mvanhorn/last30days-skill` or copy the skill to `~/.codex/skills/last30days/` (which `sync.sh` already writes to in this repo).
