xarmian 04db0c1a67 chore: add .editorconfig, golangci-lint, pre-commit (TASK-682) (#220)
* chore: add .editorconfig, golangci-lint, pre-commit (TASK-682)

Prevents style churn from first-time external contributors by
codifying the project's formatting and lint rules into shared config.

Changes:
- .editorconfig: tabs for code, 2-space for YAML/JSON/Markdown, LF
  everywhere, UTF-8; Makefile overrides enforce tab (syntactic).
- .golangci.yml: enables gofmt, govet, errcheck, ineffassign,
  staticcheck, unused. Scoped to Go sources; excludes web/, docs/,
  deploy/, skills/.
- .pre-commit-config.yaml: repo-local hygiene (trailing whitespace,
  EOF, YAML/JSON checks, merge-conflict markers, 500KB file cap,
  LF line endings), Go formatting (go-fmt, go-imports), and
  prettier for YAML/JSON/Markdown only (Svelte intentionally
  excluded — no Svelte prettier config yet).
- CI: wires golangci-lint into .github/workflows/ci.yml via the
  official pinned action (v6.5.2 → SHA 55c2c144...). Uses
  only-new-issues: true so this PR is not blocked by the 17
  pre-existing findings on main, which are tracked as IDEA-732
  and will flip to strict enforcement after they're resolved.

Verified:
- golangci-lint run with this config locally; config parses and
  --new-from-rev=HEAD is clean
- All YAML parses via yq
- go build/vet/test + web build all green

Parent: PLAN-644.
Follow-up: IDEA-732 (fix legacy lint findings, flip to strict mode).

* fix(ci): upgrade golangci-lint to v2 for Go 1.25 support (TASK-682)

Per Codex review on PR #220: golangci-lint v1.x (including v1.64.8
which I originally pinned) is capped at Go 1.24 support. Running v1
binaries against Go 1.25 source can silently drop/misreport findings,
defeating the purpose of a lint gate.

Switch to:
- Action: golangci/golangci-lint-action@v9.2.0 (pinned SHA 1e7e51e7...)
- Lint version: v2.11.4 (latest stable v2)
- Config rewritten to v2 YAML format (version: "2", linters.default,
  formatters section for gofmt, exclusions.paths)

Verified:
- `golangci-lint config verify` clean
- `golangci-lint run --new-from-rev=HEAD` reports 0 issues on the
  current diff (still well under the safety cap since we're using
  only-new-issues: true)
- Full run against main surfaces the expected legacy findings, which
  remain tracked in IDEA-732

Parent: PLAN-644.

* fix(ci): anchor golangci-lint exclusion paths + add PR read perm (TASK-682)

Addresses two follow-up comments from Codex on PR #220:

P1 — golangci-lint v2 uses regex path matching for exclusions, so the
bare patterns "web" and "skills" would also match unrelated Go files
whose path contains those substrings (e.g. "internal/websocket").
Anchor with a leading "^" and trailing "/" so only the intended
directory trees are skipped.

P2 — The workflow already grants "contents: read" at top level, but
golangci-lint-action with only-new-issues: true also fetches PR diff
metadata from the GitHub API; the action docs list "pull-requests:
read" as required for that path. Add it explicitly so the action
doesn't fall back to scanning all code and defeating the purpose of
scoped issue reporting.
