Add Apache 2.0 license

[usmansalimLM]

Licenses this repo and @likeminds.community/feed-rn-core under Apache 2.0.

Changes

File	Change
LICENSE	new — canonical Apache 2.0 text, repo root
NOTICE	new — LikeMinds copyright attribution (required by Apache §4(d))
likeminds-feed-reactnative-integration/LICENSE	new — same text, so it ships inside the npm tarball
likeminds-feed-reactnative-integration/package.json	"license" changed from ISC to Apache-2.0

Why two LICENSE files

The root LICENSE is what GitHub reads to show the repository's license badge. But npm packs
only the files inside likeminds-feed-reactnative-integration/, so the root file would not
reach npm consumers. Both are needed and both are byte-identical. This is standard practice
for a monorepo that publishes a subdirectory.

The three sample apps are intentionally untouched

qna-feed, social-feed, and social-feed-expo are all marked "private": true and declare
no license field. They are not published to npm and are covered by the root LICENSE. Their
package.json files are unchanged.

Notes for the reviewer

The LICENSE files are byte-identical to https://www.apache.org/licenses/LICENSE-2.0.txt
(SHA-256 cfc7749b96f63bd31c3c42b5c471bf756814053e847c10f3eb003417bc523d30). Please do not
reformat them or fill in the Copyright [yyyy] [name of copyright owner] placeholder in the
Appendix — that placeholder is part of the Appendix's instructions, not this repo's copyright
notice. Editing the text makes scanners report "Other" instead of "Apache-2.0". The repo's
copyright notice lives in NOTICE.

The package.json change matters as much as the LICENSE file. npm consumers' license
scanners read the registry metadata, not this repo. It takes effect on the next published
version only; 1.17.1 and earlier keep ISC on npm permanently.

This is a relicense from ISC to Apache 2.0. Every contributor to this repo appears to be
LikeMinds staff, so this should be an internal decision, but please confirm before merging.

Context: this is one of three

@likeminds.community/feed-rn-core -> likeminds-feed-reactnative       (this repo, public)
└── @likeminds.community/feed-rn  -> likeminds-feed-reactnative-data  (PRIVATE)
    └── @likeminds.community/feed-js -> likeminds-feed-js-data        (PRIVATE)

Both dependencies are private. Licensing this repo alone does not make the React Native feed
SDK usable as open source. Companion PRs:

• LikeMindsCommunity/likeminds-feed-reactnative-data#(see linked)
• LikeMindsCommunity/likeminds-feed-js-data#(see linked)

Those two repos must also be made public (a separate decision, not done by any of these PRs).

Flagged, not changed

This repo has no root README.md and no README in the published package directory. One would
normally carry the License section and explain the monorepo layout. Not added here to avoid
inventing project documentation.

Superseded by #135.

This PR was blocked by the Validate Source Branch Pattern check: the branch chore/apache-2.0-license matches neither ^release/v[0-9]+\.[0-9]+\.[0-9]+$ nor ^hotfix/LM-[0-9]+_[a-zA-Z0-9_-]+$. A PR's head branch cannot be changed, so it has been reopened from release/v1.17.2.

The replacement points at the identical commit (ecbc3ec) — no content was rebuilt or re-derived.
