fix(kyberforge): bridge apm content to Claude Code's flat plugin discovery

Claude Code's (and Copilot's) native plugin installer has zero awareness of
.apm/ nesting -- it convention-scans only flat skills/, agents/, commands/,
hooks.json at each plugin's root. Confirmed via strings on the installed
claude binary and live installs of git@holocron/gitea@holocron/kyberforge@
holocron, all reporting Skills(0) Agents(0) Hooks(0) post ADR-0015's apm
conversion. Root cause (apm_cli/core/plugin_manifest.py): apm's plugin.json
compiler deliberately strips skills/agents/commands keys, assuming the host
already auto-discovers those convention directories -- it has no model of
.apm/ being host-visible at all. Separately, apm's own bundle exporter
(apm_cli/bundle/plugin_exporter.py, behind `apm pack --format plugin`)
implements the correct .apm/ -> flat mapping, but only ever targeted
build/<name>-<version>/, a path nothing in marketplace.json's source: points
at.

scripts/sync-plugin-content.sh wraps that bundle exporter and copies its
agents/, skills/, commands/, instructions/, extensions/, and merged
hooks.json back into each plugin's own root as a second tracked
compiled-output category -- same governance status as
.claude-plugin/plugin.json: generated from .apm/, never hand-edited. tests/
subdirectories are excluded from the mirror (dev fixtures, not host-visible
runtime content; several hardcode a relative repo-root walk-up sized for the
.apm/-nested depth, which breaks when duplicated one level shallower).
Applied for real across all 6 plugins and verified two ways: `claude plugin
validate --strict` passes on every real plugin directory, and a live
`claude --plugin-dir <path> -p "list skills/agents"` behavioral test
confirms content is now actually discovered.

Also, from the same issue #90 review round:
- scripts/check-manifests.sh pointed at each plugin's root-level plugin.json
  (checking skills/hooks/mcpServers/agents pointer fields) -- that file was a
  stale near-duplicate of .claude-plugin/plugin.json nothing else read or
  wrote, now deleted across all 6 plugins. check-manifests.sh is rewritten to
  validate .claude-plugin/plugin.json instead, and drops the pointer-field
  checks entirely (nothing to check -- those fields are correctly absent by
  design). Content-presence drift is now check-plugin-content-sync's job, a
  new pre-push hook wired in .pre-commit-config.yaml.

docs/adr/0017 records the root cause and decision in full, including two
rejected alternatives (patching plugin.json's path fields directly -- apm's
compiler strips them on every run; pointing marketplace.json at apm pack's
build/ output -- a version-suffixed non-source directory nothing can install
from without an extra build step). ADR-0015 and CONTEXT.md are updated to
point at it.

| `%gd` | shortened reflog selector |
| `%gs` | reflog subject |
## Pickaxe Search: -S and -G
**`-S<string>`** — finds commits where the **count** of `<string>` changed (i.e. the string was added or removed net). Does not match commits where the string merely appears in a diff hunk without a count change.
```bash
git log -S"my_function"
git log -S"my_function" --pickaxe-regex # treat as POSIX ERE
git log -S"my_function" --pickaxe-all # show all files in matching changesets
```
**`-G<regex>`** — finds commits where any added or removed **line** in the patch matches `<regex>`. Broader than `-S`: matches whenever the pattern appears in diff text regardless of count.
```bash
git log -G"frotz\(nitfol"
```
**Critical distinction:** given a diff that removes one occurrence of `foo` and adds one occurrence of `foo` (net change = 0):
- `-S"foo"` — does **not** match (count unchanged)
- `-G"foo"` — **matches** (pattern appears in patch text)
Binary files are searched by `-S`; ignored by `-G` unless `--text` is supplied.
## --diff-filter (full table)
Selects commits (in `git log`) or files (in `git diff`) by change type:
| Letter | Meaning |
|---|---|
| `A` | Added |
| `C` | Copied |
| `D` | Deleted |
| `M` | Modified |
| `R` | Renamed |
| `T` | Type changed (regular file ↔ symlink ↔ submodule) |
| `U` | Unmerged (conflict) |
| `X` | Unknown (indicates a git bug) |
| `B` | Pairing broken |
Lowercase letters **exclude** that type:
```bash
git log --diff-filter=ad # exclude added and deleted files
git log --diff-filter=M # only show commits with modified files
```
`C` and `R` only appear when copy/rename detection is enabled (`-C`, `-M` flags or `diff.renames` config).
## -L — Line Range History (full syntax)
Traces the evolution of a specific range of lines or a named function through commits. Implies `--patch`.
```bash
git log -L 10,20:file.txt
git log -L /start_pattern/,/end_pattern/:file.txt
git log -L :myfunction:src/app.c
git log -L /init/,+15:config.py # 15 lines after first match of /init/
```
Range formats:
| Format | Meaning |
|---|---|
| `<n>` | Absolute line number (1-based) |
| `/<regex>/` | First line matching regex from previous range end |
| `^/<regex>/` | First line matching regex from file start |
| `+<n>` / `-<n>` | Offset relative to `<start>` (end position only) |
Limitations: incompatible with `--raw`, `--numstat`, `--shortstat`, `--name-only`, `--name-status`, `--check`. Cannot use pathspec limiters alongside `-L`.
## Graph and Ancestry Filters
```bash
git log --first-parent # at merges, follow only first parent (mainline evolution)
git log --merges # only merge commits (≥2 parents); equivalent to --min-parents=2
git log --no-merges # only non-merge commits; equivalent to --max-parents=1
git log --ancestry-path D..M # only commits actually on the path from D to M
git log --min-parents=<n> # include only commits with ≥ n parents
git log --max-parents=<n> # include only commits with ≤ n parents
```
`--ancestry-path` is significant: without it, `D..M` includes all commits reachable from M but not D — including side branches that merged into the path. With it, only commits directly between D and M are shown.
## git diff — Output Control
### --stat
```bash
git diff --stat # diffstat: file names + ± bar
git diff --stat=<width>,<name-width>,<count>
git diff --compact-summary # alongside --stat: shows new/gone, +x/-x (executable), +l (symlink)
git diff --numstat # machine-readable: <added>\t<deleted>\t<path>; - for binary
```
### --name-only / --name-status
```bash
git diff --name-only # only filenames, one per line
git diff --name-status # status letter + filename per line
```
`--name-status` uses the same status letters as `--diff-filter`.
### --word-diff
```bash
git diff --word-diff # inline word-level diff with [-removed-] {+added+} markers
git diff --word-diff=color # color only, no markers
git diff --word-diff=porcelain # machine-readable: +/- prefixed lines, ~ for newlines
git diff --word-diff-regex=<re> # define what counts as a "word"
```
### Whitespace Flags
| Flag | Effect |
|---|---|
| `-b` / `--ignore-space-change` | Treat any run of whitespace as equivalent; ignore trailing whitespace |
| `-w` / `--ignore-all-space` | Ignore all whitespace completely |
| `--ignore-space-at-eol` | Ignore whitespace at end-of-line only |
| `--ignore-blank-lines` | Ignore changes consisting entirely of blank lines |
| `-I<regex>` / `--ignore-matching-lines=<re>` | Ignore changes where all changed lines match regex |
